Media cue file load dialog should remember last opened location/directory

[nodiscc]

Is your feature request related to a problem? Please describe.

Every time I want to create a new media cue, the "Open file" dialog opens in the home directory. As all my samples are in a specific directory structure in /media/, I have to re-navigate to this directory every time I want to add a new media cue.

Even when the next media file I want to load is not in the exact same directory as the previous one, navigating from the previous directory would be faster than having to start at the home directory (for example /media/DRIVE1/show1/samples/drums/ instead of /media/DRIVE1/show1/samples/sfx/)

Describe the solution you'd like

The media cue "Open file" dialog should open at the location containing the last opened file.

If the location/directory is not available anymore or otherwise unreadable, it could fall back to the home directory (or the Recently used special location).

The last opened file location could be saved in the project, or not saved at all/only preserved in memory while the application is running.

Many applications that work with multiple/many files implement this behaviour (e.g. gimp).

Describe alternatives you've considered

Add my working directory to GTK bookmarks manually while working on the project for easier access, remove it when finished working.

Additional context

I expect many users to have this kind of directory structure.

I'd echo this, I was thinking about putting in the same suggestion yesterday evening. When I'm setting up a show I would also find it really useful if it defaulted to the last location that I selected a file from when adding a media file. Always starting at /home/username/Music is time consuming. I too pull everything into a folder structure for the production, in my case they are in /home/username/documents/theatre/theatre group name/production name/sound/final so each media file I add I have to navigate up one level then down six.

This has been implemented in the upcoming 0.6 version, except that it doesn't work when using the flatpak version, see flatpak/xdg-desktop-portal#796.
