The transform tool already has its most important options in the upper right corner of the 3d view instead of in the topbar. All it needs is three checkboxes from a dropdown.
I submit that there are no such people if they’re going to do anything useful in blender.
That activates a modal operator, so you can’t use it at the same time as anything else.You should be able to just click and drag (with either the lmb or rmb, depending on your preference) anywhere to box select, circle select or lasso, depending on whichever is active at the time.
Selection tools should also decouple visibility from the ability to select through the model. I can’t begin to count the times when I box selected something and pressed delete only to discover I had only deleted the front faces.
Furthermore, snapping options should be separately settable for translation, rotation and scale.
These are the sort of improvements I was expecting from the 2.8 project, not endless deliberations on how best to spite experienced users by changing the keymaps and button locations.
