Do you have the same that whenever you save an image in GIMP, it proposes you to save it to ~/Documents by default? I would find ~/Pictures more logical.
I’m running 16.04. Just tested, and it always goes to the file that the image came from.
Thanks for testing!
For me, even completely new images go to Documents:
If i open an image it always goes to the original directory when i save or export,
If i open an image and “Save for the Web” it shows a list of the most recent used directories,
If i create a new image it always shows the Documents directory whatever i save or export, except when i “Save for the Web” where it shows a list of the most recent directories i have used.
This; on all the 6 computers i have access with GIMP 2.8.16 on it / all Ubuntu-MATE 16.04 LTS
Yes, Documents can be annoying instead of Pictures, but that’s OK for me as the window shows on the left side my favorite directories
