Questions[ubuntu-dock](ubuntu)

I just upgraded from Ubuntu 19.04 to Ubuntu 19.10. This made that my second internal HDD show up in the launcher bar or Ubuntu Dock, which it did not before.

I read that I should mount it to /mnt instead of /media, but this device was auto-mounted years ago (I believe in Ubuntu 16.04 or so) and I have a lot of symlinks and other references to the path in /media already.

How can I remove the icon from the dock without unmounting it or having to mount it to a different location? I can not even move it to another location on the bar.

I want to make Ubuntu dock like Windows taskbar

Ubuntu:

Windows:

Is it possible to uncombine/ungroup apps in Ubuntu?

The big dock on the left. In other versions you could escape Unity Launcher by going to GNOME, what now? GNOME tweaks is not showing it as an extension, even though it looks a lot like Dash to Dock.

I see autohide options in settings, but no way to completely remove it and use the GNOME default.

Edit: I'm not looking for vanilla GNOME, but simply to hide the dock.

I want to add a custom program to the favourites of Ubuntu dock, but there is no option for that.

Translating the text in this image (same as above) only says:

1. All windows

2. Quit

It also doesn't appear in "Show Applications":

Is there a way for adding the program to both Favourites and Applications menus?

Say I have two Chrome windows open like this:

It seems that the most recently used window always appears on top. In other words, the "Apply Digital Signatures" was the window I had open last. If I were to switch to the window showing the new tab, then the order in which the windows are displayed in the task bar suddenly changes.

Is there a way to keep them from shuffling around? I'd like to be able to order them however I want, like tabs in a web browser. (I'd also like to put them across different workspaces.)
