Improve Visibility of the Save Button in Settings

[nanderLP]

I recently started using UKMM, and while I really appreciate the tool, I ran into a frustrating issue with the settings menu.
Currently, the 'save' button in the settings menu is placed at the very bottom and is quite small, making it difficult to find. It also took me quite some fine to figure out that I actually have to save anything, because I was freely able to move between tabs without any 'unsaved changes' prompts. It would be very nice if you made the button sticky and/or a bit larger. Thanks for considering this!

There is a sticky button at the top of the settings tab that uses the floppy disk icon, as is common in most programs that use icons for buttons

I’ll see if I can hook into the tab switching code to check for unsaved settings and disallow it if they haven’t been saved
