Is there a way to change the file picker (used for save, open, export…) in Inkscape ?
It seems like they have done it in the windows version but the settings isn’t there on Linux see reddit.
I’ve already set GTK_USE_PORTAL=1 and have installed xdg-desktop-portal-kde.
As I said, if a Flatpak app wants to access a file in the host, it can only do so via portal dialogs or drag-and-drop. Their builtin dialogs can only open files in the sandbox, which is not very useful.
