Bring back something like the old Quick replace

[StaxPy]

Hey !
Thank you for the updates, looking sweet so far !!

Tested the Alpha2 and everything looks great, except I can't find something like the old "quick" replace that puts the cursor "inside" the targeted instead of next to it. This was particularly useful when using single block placement, but not only. Would love to see that back, for detailing builds.
The other replace types are nice, well done !
