I've been using Ubuntu 20.04 for several weeks, almost since beta came out.

The snap thing is a pain in the ass. I understand the need for something like snap or flatpak. I had software too new or too old that wouldn't work because some dependencies were not updated or were too new. Snaps can solve that by allowing the developers to provide everything you need (or everything you need that is not on your system). But why would I want a snap calculator or a snap system monitor? On 19.04 it would take a couple seconds to open the calculator...thank god they reverted those apps as normal packages.

Now I feel like I felt on Windows when I had to be extra careful installing software in case somethign weird came in the installer. What kind of package is this? Is it a snap? Can I install the normal package? Is the snap provided by someone trustworthy?

I also had to install Unity. Gnome lacks support for multiple monitors. Some stuff like the dash working only on the main monitor breaks completely my workflow. Almost for every action I want to make I have to change my focus to the main monitor.

actually dash-to-dock is working just fine for multiple monitors (and given the strange UI paradigm of Gnome basically a must have). The ubuntu-dock is just a none-configurable version of that. AND in 20.04 the full dash-to-dock just vanished...

Yeah, I had to reinstall one from source. https://github.com/home-sweet-gnome/dash-to-panel
