The consistently beautiful looks comes from Oskar having handcrafted more than a hundred different puzzle piece models that together cover all the possible geometries. The models are not modified by the WFC algorithm, the algorithm just picks the right piece for every position. (However, the pieces, which are created square, are linearly deformed (skewed and scaled) to fit in the mostly non-square grid cells).
I jut begun to do some partial automation of website interaction with the extension Tampermonkey for Google Chrome to inject my own scripts on certain websites, often creating an additional control panel UI for custom actions such as scraping or data input. I use Tampermonkey in such a way that the code managed by Tampermonkey are only loading scripts that load my actual scripts from GitHub and other sources, such that I always get the latest published versions of my scripts.
Not OP, but I decided to switch to Tampermonkey after GM version 4 which broke almost all my scripts due to the GM_## api changes.
I no longer remember the exact details but it was poorly executed/communicated, and it’s easier to switch to TM instead of updating all the scripts.
The dashboard interface in TM is a lot nicer than GM too
When Firefox stopped supporting legacy extensions, the Greasmonkey developers saw that as a chance to redesign their API (to use promises).
Tampermonkey used to be open source, but unfortunately isn't any more. I still use it though, as it has better UX (e.g. nicer dashboard, prefills @match when creating new scripts, better editor, etc).
An alternative to Tampermonkey that is open source and still uses the old style of user scripts is Violentmonkey (which also lacks in the UX department, if i recall correctly).
