Bug 461686

Hello, I use Krita for texturing 3d models and I would like to speed up the export process. Texturing can require multiple changes and exports to tweak the final model. I would like the ability to change the following:

- If you have already exported an image, Krita should remember the last filename that you have used.
- There should be an option to allow the user to bypass the 'overwrite' warning.
- When saving you always have to set the PNG settings, in this dialog there should be a 'always use these settings' checkbox.

I understand that the vast majority of users will probably not require these settings but it's annoying to have to constantly click through for a tiny adjustment. Thanks.
