Where is the best place to ask questions about the Alpha builds of Cosmic?

I had wanted to ask about certain things and look up if similar questions have been already asked, such as 1. the progress of a "start menu" applet that would function like a Linux Mint start menu with a full apps list along with logout and power options, 2. Alpha 3 does not seem to disable the laptop display when the laptop is closed, which is problematic if you use a docking station with monitors attached because you have to manually disable the display, and if you forget to enable the display before unplugging the laptop is unusable until you plug it back in again, 3. installed PWAs don't have independent icons in the app tray and so can't be pinned to it 4. would it be possible to have a system for managing and organizing .appimage apps so that they can be launched like an installed app? 5. when right clicking the desktop the dialog menu is obscured by an open windows in front of it, it should open overtop all other windows 6. installed PWAs don't have an icon. 7. if the panel is positioned on the left side or right side of the screen the date and time applet breaks.

That's 7 questions alone, if I posted them separately I would likely get blocked for being annoying, and they would be quickly buried so no one could see them. it would be the same on reddit. is there a better place for them?
