[fufexan]

I myself don't have a FileManager1 interface active in D-Bus. Probably because I only have xdp-gtk and xdp-hyprland. This makes the dbus-send call fail.

I propose opening the folder with xdg-open instead. I have my mimeapps.list configured properly, and use portal activation for xdg-open. Using xdg-open also bypasses the comma limitation.

[PacificViking]

I used dbus because xdg-open doesn't select the newly created file within the window opened. I store my screenshots in the same folder.

Afaik, dbus is the only way to select a file within a file manager semi-platform-independently:

[fufexan]

That makes sense. Then we'll want to warn users if they don't have the required portal.

[fufexan]

Looks good, but --openfile should be documented in the man page as well.

Also, you may want to rebase this, as there's a conflict on the Changelog.

LGTM. Thanks!
