We could implement such feature, but there's a trouble with choosing into which directory to download. We cannot use installation dir, and the game doesn't support using home dir to keep maps or any other game data there

you may create new folder in game dir
Hedgewars 0.9.4\share\hedgewars\Data
like Download
or DownloadedMaps
or CustomMaps etc.

No, we cannot. It's bad practice and it won't work when you have no permissions to write to installation folder.

And if you use the .hedgewars directory?I don't know, with a control when map is not found if it can be downloaded in .hedgewars/download else throw error. Does it really needs installation directory for maps?

That's better solution, but requires some support from frontend. If anyone volunteer for frontend, then we could have that implemented.

I would like to help, but I'm studying for exams right now. If you give me some documentation for the frontend I'll read it and do my best to help.

it's not our problem if someone don't have access to the folder, only administrator should play/install the game hmm
