How to reproduce

Hello OrcaSlicer Team,

I am an engineer using Linux Mint (Cinnamon) and I’ve encountered a persistent and frustrating issue with the "Open/Save Project" file dialogues. The application stubbornly defaults to the /log subfolder within the configuration directory, regardless of manual path selection in previous sessions.

My Infrastructure:
To ensure data redundancy (RAID 1) and extend SSD lifespan, I moved my configuration directory to a dedicated array and created a symbolic link:
ln -s /mnt/safe_storage/OrcaSlicer ~/.config/OrcaSlicer

The Issue:
Every time I attempt to "Save Project As" or "Open Project", the system file picker opens at ~/.config/OrcaSlicer/log/ instead of my home directory or the last used path.

Technical Observations:

This behavior is consistent across different slicers (e.g., Creality Slicer exhibits the same issue on this system), which suggests a conflict between the GTK/Cinnamon file picker and symbolic links pointing to different mount points (RAID).

The file picker seems to "resolve" the symlink and automatically dive into the first available physical subdirectory, which happens to be /log.

Internal dependencies: I attempted to set the /log folder to Read-Only (chmod 000) to force the app elsewhere. This resulted in a complete application crash on startup, proving that OrcaSlicer (Bambu-based) has a hard-coded requirement for write access to this specific subfolder.

Steps I have already taken (without success):

Manually navigating and saving to ~/OrcaSlicer (the path is not remembered).

Deleting OrcaSlicer.conf and main.data to reset internal caches.

Moving all .3mf files out of the /log folder (it still opens the empty folder).

Re-creating the /log folder after deletion (the app regenerates it and immediately targets it again).

Requested Change:
Could you please implement a more robust handling of the last_export_path or provide a global "Default Project Path" setting in the Preferences that overrides the system file picker's "guesswork"?

Actual results

Expected results

The file dialog should remember the last used directory (e.g., /home/next/OrcaSlicer/) or default to the user's Home directory. It should not automatically dive into the /log subfolder, even if the configuration directory is a symbolic link.
