Also. finally the columns will be movable and re sizable, I can't wait for the next version ;)

Thanks. That is a good idea to have custom columns, and tags will be very welcome!

You can already sort and filter experiments based on any hyper parameter or metric that the experiment reports, there is no need for any custom language query. Also all created filter/sorted table can be shared exactly as they are, so you can create leaderboards and share specific filters. You can also use the search bar in order to filter based on experiment name / comment. Tags will be added soon as well 🙂

Example of custom columns is here (the screen grab is a bit old, now there is also the option of adding hyper parameters):
