Add URL to homescreen Can I somehow place a link to an URL to the homescreen without having to open it first? 

I would like to place a threema:// URL to the launcher -- of course, my browser won't show it long enough for me to choose any "Create shortcut" option, since it instantly opens Threema.
For anyone searching: Fennec Fdroid can do that with a little detour. Create a bookmark for any page and then edit that bookmark -- you can then enter any URL you like. For the bookmark, you can create a shortcut on the launcher afterwards.
