The easiest way to use textures (fill styles) from another style is to first make a blank dummy map in the style containing those textures, then in your actual map, go to Draw -> Insert file and pick your dummy map and hit ok. Once you return to your map with the dummy map on your cursor ready to place, just hit escape immediately to stop placing it.

Horrible manager office, no window....

Well, good you have us here to talk to then to ease the monotony of isolation :)

In theory, it shouldn't be a problem, because the when you save it to google drive you are really just saving it to a normal folder on your computer, and then the google drive sync client synchronizes that folder with the cloud. This is the same for other services like OneDrive and Dropbox too.

Now, the issue you can run into here is that google drive will lock the file while it is in the process of syncing it. So google drive may actually prevent CC3+ from doing a file write if it is requested at the same time as drive syncs. Usually, this should be a minor problem, as CC3+ don't write to the file except whenever you actually tries to save. You should also be able to write to the file again immediately after drive is done syncing.
