Questions[favorites](ubuntu)

I am aware that you can right-click on an application and choose "Add to Favorites". I am trying to add it to the favorites section without using the GUI at all. Everything needs to be done in the terminal or a script.

Anyone have any ideas?

This is not a duplicate of this question. That is for SETTING the favorites, not ADDING to the favorites. When you right click on an application and choose "Add to Favorites", that must run a script somewhere that takes an input of the application name. What I'm asking is, where is that script or how can I replicate it?

OS: Ubuntu 18.04 (minimal installation option):

dkb@dkb-ubu1804:~$ cat /etc/X11/default-display-manager
/usr/sbin/gdm3
dkb@dkb-ubu1804:~$ echo $XDG_SESSION_TYPE
x11
dkb@dkb-ubu1804:~$ 

I installed the following qt-based applications using apt install: dolphin, featherpad, gwenview, kate and qterminal.

Out of these, dolphin, gwenview and kate did not show the "Add to Favorites" option when I right-clicked on their icons in the launcher. But featherpad and qterminal had the "Add to Favorites" option. Why is that?

(The situation persists even after a reboot.)

Their .desktop files didn't offer any clues.

I'm using Ubuntu 18.10 with GNOME and 'Dash to Panel'. I don't understand why I can make some opened apps favourites (with right click) but not others (like caffeine). Why?

I have downloaded the latest Firefox tar.bz2 file and extracted in home directory, I added it in Favorites. But when I launch it shows the older version.

How can I add the latest version in Favorites to launch it directly from the dock?

Due to a bug/glitch, I can't use GNOME Flashback for a while. I am forced to use the new GNOME Shell layout. I'm finding it a large leap back in usability. I am not able to customize it the way I can with Flashback. It tries to pretend I am on a tablet. But that's a different story.

I have 2 versions of IntelliJ IDEA installed. When I find "idea" in the screen under Windows key ("Activities" overview), only the older version is found. I can add that through context menu. However, I haven't found a way to add the newer one. Or change the old one's path. I have tried various combinations of Alt, Shift, Ctrl and Super with both mouse buttons, but none gave me the "edit" menu item to change what the icon launches.

How can I add a custom command, or how can I change the path of an existing one?
