move app data from ~/.cache
I often clean my ~/.cache as I have just a small 32GB eMMC disk on my elementary OS netbook. But the app settings of webpin are saved there, namely in ~/.cache/com.github.artemanufrij.webpin/
Every time I try to regain some disk space (using com.github.hannesschulze.optimizer) and clean cache, I loose app icons, window size settings, zoom level, logins, in-app settings (like notifications setup in messenger.com) and so on.
I don't mind the login, if e.g. cookies would be deleted (they seem to be in separate folder in ~/.cache/webpin/). But having to setup icons and window sizes everytime I clean my disk is annoying.
Can you please move the location of these configs to e.g. ~/.config or ~/.local? Those are probably much better places for them anyway.
~/.local should be the right way to store icons and other persistent application data.
