[Gambas-user] gb3: Undo/Redo (Ctrl-Z/Ctrl-Y)

[Kevin Fishburne]

Maybe no one's noticed this but undo/redo operations are seriously 
f'cked up. Maybe it's due to a limit on the number of changes kept track 
of, I don't know. My memory may fail me, but in the past I think it's 
processed changes between modules in module-agnostic order rather than 
by the module currently being edited. It definitely has limitations and 
leaves the code in a mixed state when moving back and forth through the 
history a certain number of times.

Sorry for the vague info about it, as I'm not sure exactly what it's 
doing, but it definitely needs a second look. At some point the 
undo/redo operations just stop with the code in a random state within 
the history.

My suggestions are to have a large default history, and to keep separate 
histories per module. Maybe having the changes itemized, browsable and 
editable would be good, something like an integrated version control 
system. No biggie, just some ideas for after gb3.0 is released.
