When editing a field with a number value (or number like value) allow arrow keys (with shift & alt modifer keys) to increment/decrement the values.
Hopefully this would also translate into live updates of these properties in the preview area.
When building and working with many elements over many hours, even this small UI enhancement would take some mental strain/task shifting strain from development.
- When dealing with pixels, it would hopefully still work to increment/decrement.
- Shift key modifier would increment by 10s. (ie, + 10)
- Alt key modifier would increment by 1 decimal (ie, + .1)
This is how the inspector works in Chrome/Firefox when dealing with CSS/HTML, and it’s become quite comfortable to use in day to day webdev work.
