I dragged it afterwards and that got saved, so that’s working. Not sure if I had a bad initial value, but I think this is the first time I used the mod in this installation.
Hmm, initial value is set to top: 0px; left: 900px; in css, and it should only apply the style if the mods.obligationtracker.position field exists in the settings. I’m not sure why it would show up that way.
Edit: also, currently fanning myself so I don’t faint because @max99x is using my mod…
Yesterday I reverted my previous z-index change, so you’re probably using an older version of the mod, so you’re probably not getting it from Steam, so I just updated the .zip that’s attached to this thread which I guess I had neglected to do. 
I’m definitely using the steam subscription for the mod. I’ll double check that it updates next time I play. Thanks!
And I updated it again in Steam just to make sure it’s fully updated, though the .less file’s modified date/time is earlier than my previous Steam commit.
