Dah problem is dat a functionality mockup is quite complicated.... ;P
Rudimentary ideas, note that because of how the buttons work and the right is not bordered off, sidebar is kinda stuck to the left in this idea.
Ps.: Don't worry, I don't think my ideas are the infinitely superior ones, I simply want to help reach a consensus with the end goal of a good GUI I will never take any suggestion or opinion as an insult. We all got different view on this topic, and figuring out how to please all sides is what GUI design is all about ;P
Anyhow, to the image
Sidebar shows pinned location or current location at the top. If pinned is at the top, current location is shown beneath.
Each sidebar block can be minimized (showing only PIN and rudimentary condensed information at best (ship counts, basically) but even when condensed, display will always show enemy and friendly force counts.
And yeah, I know I didn't go into detail of the icon displays of the sidebar, that's really beyond the scope of sidebar design itself, that's a talk about information display. And equally important.
What I wanted to show with this, basically, is that the sidebar isn't ever gonna interfere with anything in the lower half of the screen, unless you pin and maximize a dozen things
The reason I wanna have sidebar to the left is basically the build queue and alert icons, chat,ping and stuff like that, we can't ignore that functionality, and it kinda needs to follow same design as the sidebar on the left imo. But maybe not exactly like this mockup. My only goal is really to not occlude the main-view unless needed... and sidebar needs to fulfill the purpose give you either minimized rudimentary count info, or expanded, give you in-detail overview over your, the enemies, and your allies, fleets.
The build-queue will have to have a minimize, default, maximize toggle as well.... when it comes down to it, it may be better to display build queue as icons but.. I am not sure 4 different MK icons are gonna help readability. Build Queue in AI War classic was exceptionally ugly (imo) but I think doing it like that doesn't exactly hurt the GUI, as long as everything has a nice look. And white icons are not a nice look (imo)
Gods, I completely forgot, but yes, build queue is at the top right in my head... not at the bottom right. I .. would honestly have to see it in action with the sidebar and build menu, chat and coop functions to appreciate where the position really ought to be. My big problem with the queue is that originally I really intended to just clone Homeworld 2 (which had a expand/minimize) build queue on the left-mid of the screen, but HW2 only had very limited build sources, basically construction modules on big-ships only. So it could display that really nice without much GUI...
Aaaanyhow, I know this post was not really about the build menu.... but it seems to me these things are kinda related. ^^
