Simplifiers for repeat styling #264
Description
When individually styling panels, I've found that...
- I want to be able to control exactly how much padding I add, so having a readout to tell me a number would be good.
- I want to add the same styling to multiple panels, so copy and paste of styles would be cool.
- Similarly, a (somehow) multi-select option that allows me to style several panels at once. Perhaps style all children of a panel, or all siblings of a panel the same (maybe a special option to "apply style to all children or apply style to all siblings in the edit modal).
