[ feature request ] support network shares, bookmarks and other locations for file selection on Linux

[GralfR]

Hi! I use the gLabel 3.99-master 564 appimage on Linux Mint 20.2 Cinnamon. Opening file/labels or browsing for an image-file does not support network-shares or other locations. If I want to import a picture from my NAS, I have to copy the file to a local drive or mount the share. In nemo I can browse to a share with e.g. smb://, which automounts it. In other programs on that system I can at least use my bookmarks or automounted shares from nemo. The file-dialog in gLabels does not support this and even looks different to others on my system: For example this is what other apps have as a file-dialog, supporting network, bookmarks and other locations:

Just for the record: on Windows 10 gLabels is using the Windows file-dialog with network-support.

Thanks
