Worked: never?
**Short description of error**
Something I stumble upon every now and then is that 'Repeat Last' (default hotkey: Shift-R) does not work after an undo call.
This is especially annoying if you call undo after 'Repeat Last' - which in turn makes blender forget what the last operation was.
I run into this regularily while doing UV's, so lets say I have called 'align auto' and then select some new uvs - then do 'Repeat Last' and keep doing this for a bit, but at some point I will make a wrong selection and hit shift-r and undo.. now I have to first understand why Shift-R is not working anymore and then search for whatever operation I was doing, this hurts the workflow fluidity quite a bit.
I know the undo area is tricky corner in the blender codebase, so I suspect some technical difficulties will make this not so easy to pull off .. or is the reason why its not working in the first place.
Did a quick search here on phab but could not find an open task for this - let's ignore some tasks from 2011 ;) - so I though I just do a small post about it here.
**Exact steps for others to reproduce the error**
1. select vert
2. grab and move that vert
3. undo
4. shift -r -> nothing happens.
Anyways thanks for your time :)
