Hey, I just played around with Blender’s hotkeys (randomly hitting buttons :P) and I got this cool idea I would like to suggest (but I don’t know where I’d suggest this)
Recreate the “Add” [spacebar] to toggle sub-hotkeys.
For example, rather than hitting Space, and then navigating with your mouse through the menu (and wasting precious time) you instead would:
Spacebar -> "A"key for “Add” -> "A"key for "Mesh"menu -> "C"key for Cube
basically, the menu would visually correspond to your keyboard, and users could arrange it to their preferences by drag and dropping different primitives into the empty keys that they like. (and maybe even save their own primitives that would auto-append from another file? Like that base mesh you made of a dog, or dinosaur or human …)
another example: Spacebar -> "T"key for “Transform” …
get the idea?
Wouldn’t this be a simple but yet useful and slightly more productive way of working?
p.s. an even crazier idea: Blender people love sharing their blends, wouldn’t it be easy to set up a server (?there probably already is one out there?) that Blender could temporarily access. So that way people could (from inside of Blender) hit Space -> Add -> Online Library … and then browse & download community contributed meshes? … and then (from inside Blender) upload their own?
