please either submit a bug report or mention it in the #questions-suggestions channel in the discord server.

depends. generally if it's about accessibility or convenience i am more than happy to look into making changes, but please submit it as a bug report or bring it up in the #questions-suggestions channel in the discord server for the migteam to look at.

latest v4 of bootstrap (v4.6.2) and fontawesome v5 free. find the bootstrap v4.6 documentation here and search for free v5 fontawesome icons here.

stick a &nb.sp; between the <i.> (type that in manually/don't copy and paste it, i've stuck an invisible period in there so i can actually display the text) tags of your icon first and then hit save. it won't show up in the editor itself, but will show up on whatever page you're using it on.

anything that goes through the on-site text editor goes through an html parser that strips out various tags and attributes for security reasons. some thing (i.e. overflow) you can find pre-existing bootstrap classes for instead (i.e. overflow-auto) but otherwise you'll just have to work around it.

give whatever you want the tooltip on the class tooltipster and then give it a title attribute (i.e. title="your tooltip text here") and it should work. normally bootstrap tooltips are through a data-toggle attribute but the html parser will strip tooltip ones, so i've added it as an additional html class.
