This is not a tutorial, just a proposal for an idea here on the forums or elsewhere; you can move this post if you’d like.
A “tutorial gallery” could look like the main forum, where each thread is represented by an image of the piece being demonstrated. This would allow us to have an archive of objects, where if someone is looking for a “how to” for a specific type of look could easily find what they are looking for simply by skimming through images. Some effects are so specific that they are hard to name, to be able to see the piece being demonstrated would make it a quick process to find tutorials that are similar to what you are trying to achieve without digging through threads.
