I tried on the previous release to resize columns in the device listing, and it didn't go well. I thought I saw someone else mention it, and figured it would correct in the subsequent release.
Alas, I still have this showing, and can't seem to resolve it myself:
I think I saw a fix for this in the current beta version, which gives an option to reset the column sizing in case it gets all screwy. So yeah, I think a work around is coming in the next major version.
