[UX] Idea: Bigger "required" indicators for fields (a red ❌ next to the field) plus a red focus "halo" around the field.

This is related to #1040.

I'm wondering if the UX would be better if instead of this:

1. fill form in a rush, but fail to notice the tiny red asterisks in some fields
2. click "save"
3. page reloads
4. see validation errors
5. fix errors
6. click save again

...we provided a better UI that guided people to this: 1. fill form in a rush, but still fill in required fields because "required" indicators are bigger and made more prominent -> get a "live" feedback/indication that you've done the right thing 2. save -> win! (at least less chances that you've done something "wrong")

Something like this:
