I've found the way the right click toggles to previous tool to be really helpful. However, every time I grab a tool other than move or rotate my muscle memory will screw me up since I use those tools so frequently that my brain expects right click to move between them by default!
Is it possible to restrict which tools can be remembered by the right click toggle? I pretty much only ever want it to give me move and rotate, and it'd be handy to be able to right click away from another tool and get right back into that flow. Create, pose, and weight tools are "one-offs" to me instead of primary interactions, and even scale/shear I use pretty rarely.
(Actually, why does the weight tool toggle this way? It feels more like a mode than a tool to me)
That said, in Unity and MAX my muscle memory for this is to select a tool directly with the QWER hotkeys. It looks like there are similar Spine hotkeys bound to the bottom row instead. That actually makes me curious about other people's workflows. How are people using the previous tool hotkey, and selecting tools in general? Would I be better off using the per-tool hotkeys instead?
I'm also curious about how that set of bottom row tool hotkeys came about. Does that mirror another application the way Unity is mirroring MAX/Maya?
