Thanks :)

It's Wednesday, So far so Good, both covers still showing up just fine.

Great, Beneath the Steel Sky is still showing the .jpeg one as well so I think that old file may have been the culprit.. I don't know how or why but at least if that has fixed it then that's good.

Was trying to browse new releases in peace... but the demos got in my eye!

:''''-(


Are you able to make a better filter then gog has?
Filter non-games & prices between not just the over & unders they've put?

danke.
I'll check it out.


Edit:

Looks like it'll do exactly what I want but something's preventing it from showing... tampermonkey says it's triggering but nothing new is showing up that I can see.

You've probably not opened the dedicated section via clicking on the table icon at the right end.
See screenshots on main github page on what's highlighted.

Thanks for trying... but there's no changes to the rendering of the site.

What's your set up?
It's working for me (and is pretty nice, I think I'll keep it) in Tampermonkey on Chrome.

Then there is probably some extension/script conflict.
Try to either turn off everything else or another browser with clean state, like by default.

Waterfox Classic, with a check for updates on tampermonkey & the script since installing the script.
Disabled all CSS, HTML & JS filtering that I'm aware of (ublock, noscript, darkreader, umatrix & your script), allowed all cookies, but didn't disable my user agent switcher which sends Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0.
No other plugins affect the webpage display that I'm aware of (they're all browser layout ones, like all-in-one sidebar).
Your script is fully working as far as I can tell (I don't see anything obviously broken & all changes are visible) & tampermonkey says the data grid is working I just don't see any changes.

Odd, I've just installed Waterfox and Tampermonkey and tried it and it works ok.

Are there any errors on the store page where it should be loading?

Web page presents as it always has (so nothing visual); console has some errors & lots of 'unknown property's: https://pastebin.com/7tVmUqK3
That's with all filtering enabled; I can post another one with out the filtering enabled if it helps.

There's nothing there that I can see related to the script, most of it is just GOG stuff or from AF.

I had a look in mine and there doesn't seem to be any console output from the other script. No idea why it's not working for you.
Sorry.

According to this, there are two variants of Waterfox: Waterfox Current based on modern Firefox, while Waterfox Classic on legacy Firefox, which can be not fully compatible with new stuff.

If the Classic variant is not a requirement, you can try to use more up-to-date version.
