Lovely. Almost what I imagined in terms of āquick changeā mechanism. You are a god! :D. I pay homage to thy magical divinity 
Is there any way to have it be moved or reduced to be more ānon blockingā of major part of the UI (esp. when I may be testing out lots of installed themes - nit picky minds of ours).
It does not darken the āUIā (as the Obs Preferences Modal) but given its own size & placement, they both āblockā the āmajority of the text/ panelsā weād love to see.
PS: As a former tech geek (whatās Obs being developed on/ in - terms of tech) and are you extending these plugins via the same?
Is it default by design, under the said dev framework for the modals/ dialog boxes to be this way? i.e. unmoveable & darkening/ graying/ blocking?
Feels a bit odd in terms of design that an appearance section of an app (Obs devs - great job but a slight oversight), pretty much blocks our ability to see real time the UI appearance weād like to tweak.
Coming from the Win32 world, it was always default for āsuch dialogsā to be moveable to side and they allowed for us to see changes as we tweaked to our visual satisfaction with an āApplyā as one continued ātweakingā until āthatās itā.
Either way 
Given that youāve gotten me with the product hat on and greedy (sorry
) also would be great to by able to pull & quick manipulate the other āattributesā & āscalingā from the Appearance section.
Maybe if Obs can fix their modal, then your plugin can take whole another tangent of evolution.
I think a themes designer & data gives a great baseline, but being able to scale up/ down the fonts & spacings (para, line, indents etc.) can be quite key, when ādata treesā and ādensityā increase within the UI.
Imagine being able to see so much āoutlinedā data on a massive 4K UHD. Geek screen estate heaven. I think some ābig complex data treesā folks would get this.
@kenset - Following up, I wonder if you saw the response and had any thoughts on the above. Would love to hear back.
