I kinda hate that thing already.
1. The search is a mess. The order of sort is bad - hope I got it fixed already.
2. I can't find any access to the forum
3. I literally are never in the shop, because it is kinda hiding in the menu
4. I have to renew my Steam connection every 3 days or so. I keep steam directly, since I don't have these trouble there
5. GOG Galaxy cannot launch because it is already running on another account on this computer. <-- NO IT IS NOT. I FRESHLY STARTED MY COMPUTER!

Jesus christ, the gui is a mess. Please keep the old one and just add the steamgames.

1. Not sure what you mean. Search is working great for me
2. Go to any games store page and click on Forum discussion. Now click on Community and bookmark that. Yes I know that sucks.
3. I think it's kinda nice that the shop is in not your face all the time
4. It's still beta
5. It's still beta, works for me though

1 not that i have noticed
2 as said, bookmark the foum
3 you can set store page as the open page
4 sounds like your network is dropping out
5 you are not running as admin

It's almost as if Beta software means that it's still not finished and in development and testing. But no, of course that's just silly. It should work perfectly right away, right?

I think we have to point at many publishers (especially MMORPGs used to do that) for keeping games "in dev" or "beta", while fully charging for them. They watered down the term "beta" unfortunatly. I doubt many still knwo what it really means: You are supposed to test the software (open beta right now: Open for everyne, used to be closed Beta, install on invite), check if there are bugs, post bug reports (yeah, that means you are supposed to invest some time and work and also try to report in a way the dev can investigate the issue) and... tadaa... post feature requests. In a factual and descriptive way, stating what you wish and how you'd like to see things.

What it is not for: To rant about the software being new, or to complain without any suggestions. As I always say "Doesn't work is no fault description" and "I don't like it" is neiter a bug report, nor a feature request. We are not ment to like any change, don't misunderstand me, but we should post a detailled report what we do not like, why and how to make it better, instead of bulletins. That's what it is all about and the only way a dev has something to work with....

all true but the devs need to get feedback as well if they want people to take time out of their day testing ui builds... otherwise testers will assume its pointless

Of course a good community manager trying to translate dev -> English, English -> dev, collecting and bundling feedback and echoing "in progress" or "not on our priority list" and so on would be nice and also rewarding. Boards that are silently read, without feedback are less effective. On the other hand it is hard to sweep through pages of "I hate it" and pick out the little grains of usable information. Now we are back to the community manager tranlating and filtering.
Rift made it right in that departmend back in Beta. You had a lot of feedback from the devs, or you get good communication with the Grim Dawn devs, with regular dev updates and diaries. So, feedback from the other side of the monitor is important too, but you can't expect much feedback if you just say "it sucks" ;)

This is no excuse, if you want my opinion (or not, you're still getting it.)

I don't honestly care what perception anyone has over the term or not. Beta is unfinished software publicly released for testing purposes. End. It isn't my fault if someone doesn't get it, I can deride them all I want because of their lack of education on what's what. I've been beta testing (both closed and open) for nearly two decades and have been invited to enough alpha tests that I'd have to actively think on it to tell you how many. I'm like Danny Glover in Die Hard at this point. I've lost the will to put up with people.

I can fully understand your point of view. I am not trying to excuse this misunderstanding, but only to explain where it is coming from. Those two motivations are hard to distinguish but completely different. I can fully understand where someone is coming from, but at the same time totally disagree. ;)
Beta does mean unfinished and only mostly feature complete. Features may be added, or removed if they do not work out in the grander scale, even though it worked in small scale Alpha or closed Beta. People are meant to be construcitve and do their best to make the product as good as possible.
On the other hand I agree that communication could be better. A list of "heard feature requests", if possible added with "heard", "in consideration", "in progress" to "hell no!" would help to keep the number of double requests lower. Some community manager commenting on decisions or progress here and there would be nice too. But that one may no result in the community discussing ad nauseum a craved feature and playing a blame game with the devs. It again means a lot of responsibility from the community.
