Hello!
Thank you all who have brought Atuin to existence!
I have been using primarily OS repo provided versions – 18.6.1 (Debian & Alpine Linux) with a couple instances of 18.8.0 from the git releases.
I haven’t strayed far from the repo version since I am using the atuin-server-18.6.1-r0 provided by alpine and didn’t want to entertain the possibility of fouling things up by wide atuin version differences.
Prior to atuin I was using the [space]command somewhat like an index in my history files. 
..so I had assorted " " imported into the atuin db. I noticed those are displayed in the list the same as those without a space.
I’d like to suggest that atuin somehow tag or otherwise visually clarify any commands starting with a space when viewing the list of commands. Ideally, something obvious more than simply showing the starting space.
EG: color the command, a glyph or whatever.
