Previously I had modified the LeftBar plug in to create a RightbottomBar as shown in this wiki - https://right-bottombar.tiddlyhost.com/ . This RightbottomBar works both in desktop and mobile mode.
Now what I am trying to do is to use LeftBar in desktop mode and RightbottomBar in mobile mode (beacuse the rightbottom is the most accessible location in a mobile if you are righthanded). I tried to port the stylesheet used for RightbottomBar to the LeftBar, but the RightbottomBar was not getting activated. Always the LeftBar was only shown. Any ideas?
