Gtk4 headerbar issue and NotifyOSD feature request (right place to suggest them?)
Gtk4 programs (specifically libadwaita programs in flatpak, needs testing in not sandboxed environments and not libadwaita apps) don't integrate properly with Unity's top menu, the headerbar doesn't integrate when maximized. I was using bottles when the issue happened.
Another bug I found is snap apps not showing the right icon size on Unity's app menu, kinda troublesome due to the focus Ubuntu has on snaps. Other bug related to Unity's menu is sections other than files and apps not showing any content.
Feature request 1#: Improve NotifyOSD or change it for something else
NotifyOSD shows the user unclickable notifications, that once gone have no method of telling the user something happened (if you go do something else, missing notifications is easy). Is adding a notification tray icon possible? It was possible using this PPA on 16.04 https://www.omgubuntu.co.uk/2016/12/never-miss-desktop-notification-indicator
I also found another PPA that shipped a custom version of NotifyOSD that allowed complete customization. https://www.fossmint.com/notifyosd-desktop-notification-bubbles-in-ubuntu/ Overall, Unity's current biggest problem is the unintuitive and most likely annoying notification system (there are cases when apps don't even use native notifications! like thunderbird or gnome-software sending notification-like popups)
Great job and keep going! Sorry if this report is unprofessional, I can split all the bugs and feature requests to ease development if needed.
