I would like to see the ability to stack commands like Terramodel.
Scenario:
Draw a line, then you want to pause to measure something, you can engage the measure command, and when you hit escape you return back to line drawing tool.
There should be no limit to how many commands you can stack, obviously some commands can not stack due to conflict with other tools but most drafting and measuring and cogo calcs can stack.
Escape key backs you out of the list, right click menu updates the recent commands showing at least 5 last used commands for quick and easy repeat command instead of wading through menu ribbons each time.
AutoCAD has a similar feature but Terramodel does this better (top section of the right click menu is dedicated to the feature, user configurable how many recent commands should be an option.
