Comment 14 for bug 1958670

I do agree with your points Grofaty, there has been some changes in the master branch just now that help with this bug (though there's still work to be done of course, this is just part of the UX aspect). While I personally think all files should have extensions, Linux as a platform has a lot of functionality that avoids the need for it, so to some users, it's a reasonable expectation that an image is an image regardless of what it's called.

Pinta can now identify your image files regardless of their extension on Linux in most cases. If you save a file as just "example", and it's a valid jpeg; Pinta will now present it in the file picker properly whilst avoiding presenting any files that aren't images. The logic here should be shared across the majority of the OS, which means that similarly, the file manager should already show a preview thumbnail and right clicking will highlight Pinta as a possible editor for opening the file, or the general image viewer application, etc, even if there's no extension.

There's still considerations such as changing the default recommended name to include an extension by default, possibly throwing a warning it one isn't included, and of course, fixing the underlying data loss bug; but the UX concerns around a file appearing to be missing just because it doesn't have an extension should be a lot better.
