I appreciate that you are constantly putting work in the layout and overall design, but this is as always mostly in the category "deceptive manipulation of user" and - more importantly - silently dropping functionality.
Firstly, please reintroduce these features, as I'd have to script and do botting on your site what you really do not want.
Dropped "select all" in the wishlist and collection.
This is my main gripe, which pushed me over the edge to write this.
Seriously, you cannot select all your games in the collection and / or wishlist anymore and expect me to go through at least 120 pages (with 96 games) on my collection to load each page, click on select all and the click on delete? Same goes on my wishlist with 36 pages (with 96 games).
Just put a reset collection / wishlist button somewhere visible and job would be done (and would be miles more efficient on the backend as well as on the frontend / browser.
Why wanting to delete the whole collection / wishlist? Because they get over time inconsistent or I just want to have the filter in the deals section just only to filter with games from a specific library, which is not implemented and is "complicated". Or I want to just start over after a major reorganisation in the original sites' wishlist and do not want to work through the gg.deals wishlist to sort out the removed games, as the synchronisation does not remove stuff from the wishlist I manually deleted elsewhere.
Yes, I tested this with multiple browsers (Chrome, Firefox, Edge), there is no select all option anywhere.
Cutting off item entries in the filter row (the "more filters...")
Nice deal that you have hidden the more useful filter options ("user", "type" (if its an game, dlc, pack ...) and "genre") away in the "more filters", so we have to click more.
Most people do have 1080p screens and if you widen to layout by half of the blank space on the right and left side, you do not need to waste space and everything fits nicely.
menu bar on the top
same deal, why are you hiding your own community forum (if we ignore the voucher stuff)
You moved the most used features to the right side, so the people who read usually from left to right see these options at last, in order to make it more complicate to use your site and extend the time the people staying here. Probably an ad / tracker thing to earn more money. Nice job.
It is ... too busy.
And you load everything all at once and you don't open subpages anymore.
Really learn some basic ergonomics. This is really unwieldy clunky and resource hogging if you load everything into one big huge page?
