Hi @stevebaer,
Unfortunately, the Edit code… window of ghgl v7.1.0 - installed through PackageManager - still doesn’t appear to be working right in the latest, stable release of Rhino 7 (7.2.21012.11002, 2021-01-12) for macOS.
At first I thought that the previous issue with the window not popping up at all, still wasn’t fix. Then I noticed that it simply opens behind the Grasshopper window!
Like at Playboy Mansion - where everything that happens in the grotto, stays in grotto -, the editor window also remains positioned behind the Grasshopper window no matter what!
Guess I need to wait for another update. 
Addendum
Setting the glLineWidth… parameter for the GL Shader component also does nothing. The displayed line width remains the same, whether I change it to 0.1 or 16.0! However, glPointWidth… seems to be working fine.
Addendum II
Wow, otherwise the code editor is great. Your autosolve works fast and code completion is snappy, too! Can you please implement these amazing changes in the GHPython component, which editor-wise has been - sorry - a trainwreck since Rhino 5? Great job!
Addendum III
Using _time also doesn’t seem to work! Nothing is animated, but when I constantly recompute things move.
Addendum IV
Each time you double-click the GL Shader component or select Edit code… while right-clicking on it, an individual editor window gets opened! I didn’t notice that, until I tried to close Rhino (and it crashed). The code editor windows were hidden behind the Rhino window.
