They were not asking for it, but seem to use it and they would like to extend the feature of these apps. And there are people to integrate a wiki, mail client (even mail server: Nextcloud Mail Server), and many more app ideas: https://help.nextcloud.com/c/apps/app-ideas
Well if they make user experience worse (at least in your case), they perhaps didnât see this use case. There was a discussion about the three dot menu recently (Generic UI discussion.. "three dots menu"), as useful as it might be on a mobile device (where I rarely use the webinterface) but it is painful on a desktop computer. And you could detect if the page is accessed through mobile or desktop.
So reverting it back to the previous version would make it an enhancement and you can request it.
Before releases, they invite for some beta testing and like to get some feedback. I usually just check out my basic use cases, if I see any problems. However, I though about setting up a very basic test system (like raspberry pi) and just benchmark the pure sync performance.
Polls are not used here on a regular basis. I thinks itâs a great idea to get a better feedback from the community to improve Nextcloud.
