It took me less than a minute to install Stylus and import all my userstyles from Stylish.

The headache for me was that the stylesheets are transferred, but the applied domains are not.

I've got a system where I use a set of standard styles applied broadly against many sites.

E.g.,

Annoyances -- applied globally to all websites by default: https://pastebin.com/raw/GrE9KX6D

Local Gifs: https://pastebin.com/raw/tn7cqGtJ (Exceptions to global gif filtering)

The following break on many sites too much to be applied as default, but can be used fairly generally to selected sites as needed.

Animations blocking: https://pastebin.com/raw/7Gjxj6AT

Headers / Footers: https://pastebin.com/raw/PsXWhUGf

Popups / Overlays blocker: https://pastebin.com/raw/VcgNNwDp

"Unstyled" CSS: what I apply to unstyled / minimally styled pages: https://pastebin.com/raw/rtfev3vj

For development / testing / debug:

Debug CSS: https://pastebin.com/raw/Z3kFrRQy

(Highlights class/id and entities in page.)

You must have done something wrong, of course the applied domains are also transferred. Maybe you didn't use the export function but just copied the source?

One of those (either annoyances, headers, or popups) broke a fork of Stylish. I'd click on the icon in the toolbar and the drop-down wouldn't appear. I noticed the user style also broke AWS navigation.
