personally i’m hugely disappointed with this release. it appears next to nothing has been done to improve zb’s pathetic and imbecile object / palette / tool management. yet another iteration of the app gone by without any apparent concern for the most simple and basic functionalities that would refine its use :
where’s the ’ subtool master ’ operations embedded into the core ui ?
where’s the ability to interactively and selectively remove tools from an ever expanding and cluttered tool palette ?
where’s the ability to click and drag to reorganize subtools in that palette ? to interactively lengthen and shorten that sub window ? to do something as simple as hit enter to commit an entry in a text field ?
.
the list goes on. zbrush has always been and sadly still remains the programmer art of workflows

The software controlled sample rate was introduced in 3.5, it seems to be too low IMHO . . . a max around 1000/sec would be better I think.
