Command: smarter repeat #55
Description
If we have time, we should take a look at the repeat (.) operation to make it a bit more intelligent. It should probably ignore selection and movement commands, and instead only focus on operations that actually modify the tree.
This could be helpful in the following way: say we want to select a bunch of nodes and surround them with individual cuts. If we wish to do this for a completely different set of nodes, we'd have to move over there and select the ones we then wanted to also surround. Pressing (.) under the current system would do absolutely nothing, as the repeat would be checking against the move/select commands since they were the most recent. If it ignored those, then we'd be able to repeat more interesting changes.
