I find that the "hitboxes" for single-click selection of individual units can be very small and hard to click, requiring three or four attempts to successfully select the unit. While box selection can be used in some situations, other times it is impractical. I suggest that the "hitbox" for single click unit selection be made larger. I hope others will agree.
I like this idea, it is really hard to assist a bot fabricator. It is just simple that I can't click it.
That's a great example, but there is a trick you can use. Instead of trying to right click the unit, use the "assist" hotkey or button and then spam click (attempting to click on) the fabber. You won't end up issuing a move command that cancels the assist command that way, even if you miss with some of the clicks.
