I installed uber-juno 0.3.0 in Atom 1.48.0 and let it set panes to be opened automatically (however that option was named). However, I didn’t understand that it opens the Juno panes for all file types (not just Julia files), and couldn’t find in the settings for either uber-juno or julia-client how to turn that off (which is a different issue). So I uninstalled uber-juno and the other packages from JunoLab, with the intention of reinstalling but not choosing that option to open the panes automatically.
On reinstalling uber-juno, all I have is the uber-juno package. None of the other packages were reinstalled.
