I like save. It’s an extra step to ensure the permissions are correct. Without it, if I select the wrong group in the dropdown and click the , they get access immediately, without an opportunity for me to fix it.
One thing that makes this slightly more complicated is the “Save Category” button applies to content on all tabs/pills right now. The warning should probably apply if you’ve made changes to ANYTHING on any section if you hit the X.
The save category button will trigger the warning if the user changes one of the dropdowns and doesn’t click the plus button. They can click save again and it will ignore the pending change and save anyway. Clicking the plus button will reset the trigger, so if they don’t change the dropdowns after clicking the plus button, the warning won’t be triggered.
Also I changed the plus button color to primary so it stands out a bit more.
