How dare I polish and remove kludges from previous releases. ๐
Also, none of those kludges would have even been necessary if the project scope was properly defined from the start and the project manager didn't let the users keep trickling in new requirements without also extending the deadline.
So yeah, how dare I go back and implement something the way it should have been done the first time?
This is true. However, changes aren't always bad. Messing up keybindings and just moving around stuff just so that it looks "cleaner" is the absolutely worst thing to do. If you decide to completely redesign your UI you should at least give Users the Opportunity to still use the old UI. This way new Users can start working with your new UI and the rest can, if they want, learn the new UI.
This is especially the Case when you redesign your UI in a way so that its more Intuitive to new Users.
