Okay, then I put my changes for the menu bar here in case anybody is interested in it. Thanks again for the hints and the help, adaliabooks and Maighstir!

// remove the purple bar above the menu bar, make the menu bar smaller and change the color to a brighter gray
addGlobalStyle('.menu::before { height: 37px; background-image: none !important; background-color: rgba(80, 80, 80, 1.0); }');
addGlobalStyle('.menu { height: 37px; box-shadow: none; }');
addGlobalStyle('.menu__container { padding-top: 0px; }');
addGlobalStyle('.menu__logo { line-height: 37px; padding-top: 0px; }');
addGlobalStyle('.menu-item { line-height: 37px; }');
addGlobalStyle('.menu-link__dropdown-icon { top: 14px; }');
addGlobalStyle('.menu-submenu { top: 37px; }');

Now I only would like to remove the darkening of the page when you access the menu and make the menu faster, but I'm afraid these are javascript functions and I have no clue how to search for them...

Edit: Found the solution in ssokolow's user style.

Same here. That's a good point. Maybe I'm still going to install Stylish.

Here's a little something to shove the account dropdown back over to the right side of the bar.

.menu-account {
position: absolute !important;
right: 90px !important;
}

(I don't have time to come up with a more proper way, but it works for my needs.)

The fading is actually a CSS animation and you can kill it off like this:

.menu-overlay { display: none !important; }
.menu-submenu, .menu-triangle { animation: none !important; }
.menu-triangle { opacity: 1 !important; }

(I discovered that with minimal fuss by hovering over the menu to make it appear, right-clicking, and then using the arrow keys and Enter to select "Inspect Element" and navigate the DOM inspector.

That'll get you down to just the lag from using JavaScript to show the menu rather than CSS :hover

Same for me.

Well, they still work in the totally optional Galaxy client, from what I've heard...

Y'know what? I'll just make my tweaks into userstyles. Here.

* GOG.com - Practical Header Menu Tweak (Un-pin the header and remove the animations)
* GOG.com - Account menu on right
* GOG.com - Center menu triangles

...and there's also this which I use to remove the colored strip but can't take credit for. (Thanks, Maighstir)

.menu::before {
background-image: none !important;
}

Yay for reply notifications not working...

Thanks! Works just as it should have worked in the first place...

Sorry, all this web stuff is new to me and I still try to learn how to use it. But I guess I have to learn it quickly as web pages get more and more annoying and I want to be able to fight back.

Okay. I can ALSO confirm no notifications.

Yeah, there is actually no system for notifications in the current menu bar at all so either they are working on implementing it later or have changed or scrapped the system entirely...

Which it is remains to be seen.

Sorry, rolling this out with no working notification system shows some serious lack of sense at prioritisation, imo.

I'm undecided if I'm more annoyed that they killed the notifications, intentionally or by accident, or that they keep mum.

Thanks a bunch for this. I was planning on getting to it later today, but you saved me the trouble. I just moved it a bit more to the left, now I can reach it without having to change the position I naturally place my hand/mouse at. :-)

It seems there's still a difference in menu bars between the forum and community wishlist and the rest of the site: I had a look in IE and I'm finding that on forum and wishlist pages the dropdowns don't work. All that displays is the little triangle at the top.

That's what I figured out, too, but then I kept thinking about what everyone was saying about the extra space it took. So instead of removing the image I simply pushed the menu up: The image is still there but off the screen so it can't be seen at all, and the space is recovered.
