Would it be possible to have the JSTREE menu to actually interpret html?
When I use html code in a Description, the html does not get interpreted, so when hovering over a subfolder containing a description, I get raw html code shown like this:
Unfortunately, this is an artifact of your browser. Browsers display the title attribute of links, but they will not render the HTML. The only option would be to disable the title attribute altogether (or change it from displaying the description to the folder title, but that would be useless as it would simply repeat the name of the title).
Another option would be to have a jQuery/javascript tooltip for the html gallery replace the native browser-function. This would be something for a future version of course ...
