Hi Kovid,
I found two little errors (maybe you have already fixed them):
If I undock a window from the editor GUI (a nice feature in the editor), it works fine except for the inspector, what shows an empty window. If I dock it back to its place in the GUI, all code is shown again but loses the actual position and start have the position at top of the file
If there are blank lines in a text (with or without a blank character), they will not be shown in the file preview window. When I replace the blank with ‘ ’ the blank line will be shown
Edit: Ignore the last one with the blank line. You did fix it with the new beta-update. Thanks.
