Daniel,
I tried Bloom on Ubuntu 18.10 and things have partially improved.  Left
mouse clicks inside the text boxes now move the current selection point in
the text as expected.  Left clicking on the gear button usually brings up
the Styles dialog (a javascript dialog), but the next left click always
closes the dialog without allowing the user to actually do anything.  I
wasn't able to install Bloom on the build for 19.04 because one of its
dependencies had a dependency that couldn't be met.  (chmsee /
libwebkitgtk-1.0-0)
(We'll probably phase out using .chm help files in the next year or two,
but haven't come up with a suitable replacement that all of our projects
like yet.)
