Save files without prompting for location/filename

[9a3eedi]

Hello, I would like to suggest a QoL feature.

Currently in WALC 0.3.3, when someone sends you media (e.g. an image or video), and you'd like to download it, it first downloads it in the web interface (probably to a temporary location), then prompts you to save it in a folder using a file picker dialog. This needs to be done one-by-one for each file you'd like to download, which is very tedious: (click menu button on the image, select download, go to the file picker (which for some reason is out of focus for me, maybe this is another bug or just my distro), and then press save).

Ideally, I'd like to be able to choose a "Default download location" somewhere, perhaps in a config file, and then all downloads would simply go there, similar to how modern web browsers work, and how whatsapp web does it.

Another thing is that occasionally I receive multiple images all in one go, so their timestamps are the same because the granularity is not very high. When I save them, the filename needs to be modified manually because they overlap.. this makes it more tedious. So when generating the filename, it should try to make sure that there aren't duplicates.

My system is Manjaro Linux with KDE Plasma 6 on Wayland. I install WALC using the AppImage release in github.
