Feature Request: Custom Columns

[Qwlouse]

It would be very helpful, if it was possible to add and remove custom columns from the overview.
E.g. a way of adding a config.learning_rate column.

I want this feature too.
May be there should be a check list to decide what columns are displayed, like the web interface in Sumatra.
It would be very helpful ,if some interface is added to show columns of target soft version, links to output files, comment...
