1. left click selection as default 2. maya style viewport navigation 3. add to/remove from selections with shift/alt (perhaps that's the default already? i confess mine is all custom) interface-wise: proper on-screen gizmo, ability to customize the tool shelf with drag&drop/GUI editor, preselection highlight for components…
Yea, both Max and Modo use the number keys to select component type. But Modo also optionally lets you select the component type by simply middle mouse clicking over it (so if over a vert it'll switch to vert mode, same with edges and faces). I wish every 3D app let you select the component mode like that.
@musashidan If you're talking about "Preview Selection: Multi" then yea I completely forgot about it. The problem is it shows all components from all modes at the same time, which I have never found a use for in Max, and just clutters up the screen with visual noise. Ideally you'd just have a button that turns it on, fires…
@PolyHertz No, it has nothing to do with preview selection. It's called 'sub-object pick' Assign your hotkey and press it in the viewport over the different sub-objects to switch to that mode. It is a bit buggy, though and was never really perfected after it was introduced.
