Feedback on the new Fusion UI design

I attempted to switch back to the old UI (commenting on both the space-hogging menu sidebar and my momentary panic at the circle/X placeholders, in the folder view, for scenarios with less than 4 modules--I don't recall now what the old view was exactly, but for a few seconds I thought some of my modules had disappeared).

I got a 404 page not found error when clicking on the switch back button.  I currently have an open support ticket.  Clearing the cache/cookies for the site allows me to log back into Fusion (seeing the new UI), but I keep getting the error when trying to switch back to the old UI.

I also found documentation relating to the change (the legacy UI is apparently going away in August), but I knew nothing about the change until logging in today and seeing the new UI.

Using the full text search is also hinky. I'm used to putting my data into the field and hitting enter. Now, when you do this, the page reloads. Instead of hitting enter, you have to wait for the results to load. This is bug, not feature.

One thing I really wish they would have included with this UI update: When designing new complex scenarios, it would be nice for each path to be numbered to know the proper order. Using the magic wand to do this is annoying.

I want to off road a little bit: Did anyone from Adobe let you know that this was coming? I'm the platform owner and no one told me any of this.

• No one told us that Fusion was being added to our Adobe Admin Console. On Monday, I couldn't get into Fusion. Neither could my co-admin. I had to submit a ticket in order to find out that I wasn't added as an admin in the AAC.
• No one told me that these UI changes were being made. I only discovered this ex-post facto by going to the releases page. (Usually this stuff appears as WF announcements, which didn't happen this week.)
• There was a lot of weird system nonsense happening throughout the week. In hindsight, I'm assuming it had to do with these changes happening, but again, no one told us that maintenance was being done. 
  • Timed scenarios stopped working on the schedule set. They would activate two hours behind the times they were scheduled
  • For a short period of time, Search modules were not available for new scenarios.
  • When I reported these issues, of course, the first answer was "iTs NoT uS iT mUsT bE yOuR sCeNaRiOs" instead of "Oh, we're doing maintenance right now and there may be some issues here and there."

Under normal circumstances, I try to stay abreast on Fusion and WF updates. However, after 24.5, I spent two weeks in hell trying to figure out why custom forms were being removed from some of our documents. Suffice it to say, my bandwidth was limited.

• execution history detail loads even slower than before, if ever. 
• cannot right click and open execution history from the "history" view...weak

Pros:

• data store line item turning white when cursor hovers over it does make previous selection clicking much easier

I like that the nav bar no longer overlaps the sub nav bar, big improvement there. Other than that it's meh. No complaints but not really better either.

I do like that the DevTool is now part of it instead of having to instal the Chrome extension
