Not much to say, when I open Orion the tab button Is big and the search bar small
Orion, OS version; hardware type:
Orion 0.99.114-beta, MacOS 10.14 Mojave Macbook10,2
Are you sure this isn't some weird flexible spacing problem you have?
Try going to View -> Customise Toolbar... and clearing everything then dragging the default set into the toolbar.
It was a fresh install so I didn't made any change yet.
Just tried to go to view> Customise Toolbar and Orion crashes. Log
