So, everything is working great so far, but two quality of life improvements:

1. Can we have a total achievement # count as well as the percentage display?
2. When you switch on a filter and then move to another bookmark, the filter is cleared. When you go back to the old bookmark it's still cleared. Can the filter be latched on and carried through bookmarks?

Regarding 2, for the filter to be saved to that bookmark, you need to go to that bookmark, unbookmark, apply the filter then re-bookmark it.

The bookmark is not automatically updated when you apply a filter, you have to re-bookmark it after doing so. Otherwise the program assumes that's just a temporal change and not you wanting to modify that bookmark.

I had no idea. That's definitely helpful to know, but it's not quite the same. What if you wanted to move through multiple bookmarks with the filters on?

Hmm, you create the filters and their associated bookmarks beforehand. So you can move (or I assume you mean 'view') the games in one bookmark, as opposed to another (also created beforehand). No saying it's not a valid request... but in what situations or games would you need (or prefer) achievement # count as opposed to percentage? Perhaps, for games with a lot of achievements (and some of them really hard to get)... one would still feel accomplished by the achievement # count...?

Pretty much in every situation actually. It's just easier for me to visualize how much I've done (and have left) if a game shows #/X achievements to me than an arbitrary %.

I could have 3/4 in a game and have 75%, but if I'm looking through my games to see if there's anything I can try to go for to complete there may be tons of games where I have more complete percentage-wise but in practice trying to go for that one left over achievement could be more attainable to me than a game where I have 75/100 achievements done. Both would show up in the same place on the list for me (or imagine in a game where I have 82/100 - that game is now shown above the other one.)

When you have over 1000 games showing up in GoG, more information is never a bad thing to sort by (or even just have visually).

Gotcha. Specially the last sentence. :)
