I’m definitely happy to see that improvements are getting made, and especially happy to be able to turn off the beta when I face issues such as these (some other recent changes were pushed way too early). The speed of the old explorer certainly needed to be addressed, and I’m glad the new one is decent as-is.
I do wish there were a public issues page (such as JIRA or GitHub Issues), as the DevForum search is a little finnicky when trying to check if a bug has been reported or not. It would also help developers know whether they have been heard or not.
For betas you don’t have to worry about this. You can be quite confident that beta projects are tracking every single piece of feedback which has shown up somewhere in the beta announcement post.
Of course, that doesn’t mean the team will have time for or agree with every piece of feedback but for betas it’s unlikely that any feedback is slipping through the cracks. If anything the teams often wish more people would try the betas / post feedback than actually do.
Couple bugs I just encountered. Not sure if these have already been mentioned:
Go to drag an object from one place to another in the explorer and keep your mouse still after picking up the object; you are unable to scroll the explorer with your mouse wheel. Then try the same thing but while randomly moving your mouse; you are able to.
While a script is open in the editor, you are unable to delete objects with Backspace or Delete and unable to duplicate with Control + D; but if instead you right-click on an object in the explorer while a script is open you can still perform those actions from the context menu.
