Tried UI Builder, loads of issues

Today I took a first look at the UI Toolkit and Builder package.
I've installed:

• 2020.2.1f1
• UI Toolkit 1.0.0. preview 14
• UI Builder 1.0.0. preview 13

I'm not sure if I do things right as I see some pretty nice GUI's created by other users but my experience is completely different from what I see.

My first impressions were nothing but to call the package an abomination above all I've seen so far from all Unity packages. For some reason I simply can't seem to use the UI Builder without any issues.

Let me explain why (just a few of many)

• It's incredible slow, every simple change takes about x seconds to take effect. I remember someone of Unity who said that Unity UI and workflow should comply to Google standards of not having more then x milliseconds of a delay. Well, the builder doesn't meet that expectation at all.
• Color selection wheel, just doesn't work after few clicks within the Builder GUI. Everytime I try to select an alpha value, it just closes the color window.
• When saving, your complete preview of de created UI is totally screwed. To make it appear as how you designed it, you have to save, close the builder and reopen de UIDocument. And this is every single time you save something.
  
• Editor Console is spitting out loads of errors while working with the builder, maybe this is slowing down the Builder GUI itself.
  

And the list goes on. I've spend 2 hours creating something simple and get it perfect. First I had to get used to the new idea of all inspector values, how to setup everything and such. Then I tried to create a simple UI, which took me 30min with the current system and I don't even feel I made something that works. Compared to the current system in which I create this (from screenhots) in under 1 min.

I hope I'm doing something wrong because for me the UI Toolkit is far from useable. I wonder if anyone else experience this?

 

Could you please clarify which version will have it embedded? 2021.1.0f1 still has the packages in package manager, however I thought there was a mention that from this version, it should be included. Thanks for info.

 

I was excited the day unity announced this, and I watch their progress from time to time. Today I wanted to try it and sadly i had your same feeling. I know it is a "work in progress" and we (users) has to constantly be feeded with news but, I encountered so many obvious problems that I wonder if is the case to show it to the world instead of just work on that and release when it is ready.

I hoped that would be game changer for the well known slow UI system but as is it is far far away to be usable, when, sincerely, i expected a bit more seeing the 2 years passed since the announcement

Just to add a new test case: i simple created an uidocument, 1 scrollview with inside 3 columns of text component. builted for android (an android H96 Max, not the best android device, but a low end/average device) and, it crashes almost immediately

 

It is unfortunatly far easier to deal with hand-written UXML and USS, particularly if building complex UI systems arount UITK.
