Is there any tool I can use to sync the userscripts easily? last time I checked it requires some clicks and browse files. I want them to be included in my dotfiles and automatically synced on git pull

How about [TamperDav](https://github.com/Tampermonkey/tamperdav) - It's also worth noting that Tampermonkey supports syncing to Google Drive and Dropbox (though you don't get the same sort of version control) - I use dropbox syncing, then host my userscripts on github gist then install from there, that way they auto update from gist.
