• Added loading and error modals
• Added restore bands button

NOTE: Cell locking functionality is still under development. Please test the band locking first.

This will be merged after reviewing the current issues with the installation process. Will probably need to move toward individual file downloads directly to the intended directories and a spread of "sleep 1" commands.

Cell locking functionality added.

About the installation, that's noted. I will also use git ignore for my next PR to avoid merging outdated local repo script contents.
