Quite some time back we installed the shoreditch theme after some cheerleading by @NNichols

The shoreditch theme was a big improvement but it has a slow maintenance cycle which led to it being forked by Mathieu - who also simplified the code a bit as code maintainability was tricky I think. That theme is 'The Island' https://lab.civicrm.org/extensions/theisland

Per the readme

"The name of this extension continues the tradition of naming themes after places. It was forked on the island Montreal, but it also a nod to all sorts of islands out there, such as Snake Island ("Russian warship, go fuck yourself"), islands going under water due to global warming, islands exploited by colonization, desert islands, etc."

I've thought for some time we should switch but the recent upgrade makes that pithy because there is a UI bug that affects shoreditch (at least our old copy but is likely unfixed) and not The island

(look at Soft Credit being unlabled in the top one. The personal campaign pages section is probably disabled on prod but not my local)
