Good to hear. I was a bit confused because it sounded like a problem that happened in an older version. I stopped using blank spaces to allow moving of jobs around with the current versions. You shouldn't see the problem with the latest version. Also be sure you have version 0.3.4. I just updated it a few minutes ago. If you see that problem again just screenshot it. Also if you see anything that should be changed with 3 columns I might be able to do something about it. I usually like it at 5 columns so I design it with that in mind.I have updated to the latest version, and so far no issues with 3 columns instead of 4, but I've also deleted some jobs in the mean time.
