[dev] GUI Design Guidelines

TODO Add some more here

1. Follow the [dev] Translatable Strings page.

2. For capitalization in GUI labels, we currently follow the AP guidelines (Associated Press Stylebook). You can use https://titlecaseconverter.com/ to check, AP is the default there.

3. For ellipses etc. in link texts:

   • Use .. for all submenus
   • Use ... only for links that need more information to perform the action (see here as well)
     • For example, "Move To" on a plugin should be "Move To...", because we need more information (to what point in the LO are we moving the plugin?).
     • On the other hand, "List Masters" on a plugin should not be "List Masters...". While it does show a popup, that popup is the whole result of the command already! We don't need any other information from the user to list the plugin's masters.
   • By doing this, we follow both Microsoft's and Apple's UI/UX guidelines for ellipses.

4. Avoid hugely long context menus. Especially without icons (which we currently don't support - TODO look into that) these make it really hard to spot particular links. As a rule of thumb, once you're near 15 or so links, it's time to consider submenus.
