Hi, ambient-whisper 
well if you like it there is no reason to change it 
I personally don’t like XP shell…
As fas as my OS is concerned, I bought windows XP separately from my computer… I don’t allow OEM version of windows on my system… Nor do I allow the factory restore disks restore BS applications… I have just a Raw version of windows XP, and I manually add my device drivers, an run TweakUI from Microsoft to achieve total minimalism…I disable allot of thing in windows that I don’t use.
I also have a few accounts on my system for various tasks…
For backup, I have a vanilla version of windows XP, no whistles or bells… then I have Black box account with all the whistles and bells, then I have a Video game playing account, which is TOTALLY MINIMAL… it has nothing to speak of… I used the device manager to make a Lean system, and I have disabled un-needed things, just stuff relevant to game play (It makes a BIG diffrence)…
As far as production is concerned, I cant go back to the old way of hunting for the start button… or littering my desktop with Quick launch and Icon shortcuts… nor do I like clogging up my ram by assigning hot keys for tasks…
In black box I don’t even minimize windows anymore, I just leave them open and switch desktops…
this way I can keep relevant programs on the same desktop Eg… On my first desktop I have it set up as my communication center…
I have a Radio station list, Win amp, E-mail client, and X-chat there all opened and positioned on the screen… when I need to do any INTERNET tasks I switch desktops with my mouse wheel, or by bumping side of screen.
this way I don’t have to “Juggle” windows from the task bar, and resize/reposition them, they are always there open and ready to go…
It is like having 4 monitors…
I can have Brush open full screen, paint shop pro, and my choice of UV mapping software on another Desktop, all sized and fitted… It takes me less system recourses to just leave them open… minimizing and maximizing suck lots of system recourses to redraw the window. the way BB4Win is set up your GFX card thinks you have a 6 foot wide monitor, and once the window is drawn that is it…one good trick I have learned is to get all my application I am using open, and in position, then I run a RAM defragger/optimizer… I sometime gain 3-5% depending on the applications I am ruining.
As far as the right mouse button is concerned, it is Way faster to get where I need to go, and to do the tasks I need…
I have bad wrists from using mouse too much… the menus save me from a bit of pain, I can get into my Zscript folder in 2 clicks rather than 14 clicks, plus I don’t have to wait for windows to Draw new window/Icons… it is just a text list. sure I can make a shortcut on desktop, but that is a waste of disk space, and I only need to get into My Zscript folder maby once a month… and Icons get covered by windows…
I have quite a few different folders I constantly use, Models, textures, download,upload, HTML, VRML, notes, Etc…
instead of having Icon shortcuts that my windows can cover and hide,I only need 1 pixel of the desktop showing to access ANYTHING on my entire system with the right click menu I have written. I don’t have to reposition the windows to see Icons under them.
I have shortcuts to Heavily used folders/applications right there, my entire control panel, my start button menu, my shutdown/log off menu, my INTERNET favorites…
I guess the BIGGEST thing I like is that it turns the Window$ key into just a modifier!! it doesn’t interrupt anything anymore when I accidentally hit it…
In Brush I CONSTANTLY was hitting the windows key trying to hit ALT- or Control… the way it is now, if I hit it it dose NOTHING! in the past it would knock me out of Brush, and make me loose my train of thought… version 1.55b used to crash when when start menu popped up.
Black box is definitely not for everybody… it is allot of work to set up…
But:
It Looks AWESOME!
Smaller Foot print in memory (even smaller no that I use BBmemshrink
)
fast access to entire system, all I need is 1 pixel of desktop showing.
It is Fully configurable, I can add or remove features I don’t need…
It works the same as my Linux version of Black box, sometimes it is hard to tell which OS I am in.
Some programs load faster.
Everything can be configured and tweaked… it is an open source project, I can re-write the entire core if I needed to… Windoze I have to wait for new version, and just hope for the features I want…
Everything on desktop can have Auto hide, and transparency, to keep it out of the way. plus I can scale anything I want to make it smaller or larger…windows task bar has to stay Opeq, and there is no way to make it smaller… and if it has to run entire span of screen…Quick launch bar dose not have auto hide feature when it is detached. Icons have to stay all the same size also.
well I can go on and on about this…
Black box is not for everybody… especially people who like Windows the way it is…
it is not for NON-DOS users.
Nor is it for people who don’t like tweaking things…
I can guarantee that if it is set up correctly a user can access folders and files faster and with fewer clicks… plus they don’t have to hunt for Icons or start button. users can define command line switches and options to make things easier.
there are ways to get windows to do allot of what I am talking about with other applications so you can still use the XP shell… there are Numerous Virtual desktops out there… there is a way to modify the desktop context menu, and there are ways to reduce/defrag system ram… Win XP is still a good OS shell in my opinion…
just not my OS shell of choice
