feature request: automatic fill-in of and-or and easier to find classnames (customcss)

[gaygoblin]

What do you want to see?

Currently, classnames for Customcss must be found in the chromium dev-view or something similar, an often clunky tool that ends up feeling quite finnicky and annoying to work with (or against). My proposal is that a autocomplete for Classnames in the custom css and/or a easier, perferably inapp method of finding the classnames is created.

An example of the autocomplete im thinking of

[class^="tip
> tippy
> tippy_base

A possible easier way to find classnames is to have a "Dev mode" (not much unlike the awful devtools cursor search feature) where things under :hovers and the like will still show up, but with a tooltip with the associated classname on hover. It would make the themeing process a hell of a lot less confusing and far more enjoyable.
