Thanks for the reply, the feature request I was asking about is a sort of tool recall override, based on the fact that one tool has been selected from the menu and the other using a shortcut. The reason behind it is that, using a shortcut is as fast as using a right mouse click, so there is no point in having both activated, so leaving the right mouse click to reselect only the tool that was selected from the menu would save time and mouse clicks.

So, for example with the feature:
I need to create two quads; I select the line tool from the menu and start making my corners, I then select all four edges and press the "E" key on my keyboard which was assigned to 'Network", I now see where the next shape should go, so; I right click and instead of recalling the 'Network' tool it would bring up a line tool, which was not used last, but was selected last in the menu, I would then press the "E" key next which my hand has been the whole time.

Thanks for the Plugin Gallery tip I didn't know about it. I will go look around it.
