No, I mean when multiple files of the same project are open in the same window.
And it gets worse.
If you make a typo e.g. type SetTxetFont by mistake, it very nicely displays the error in the message area and highlights it in the display. This is very well done.
However you cannot (apparently) correct that error without picking the mouse up and clicking the focus back into the edit window. On Classic you could close that message window with F2, and it re-opened if needed which was a bit irritating but only that. This would drive me mad inside half an hour.
If TGC want this to be used seriously it is desperately in need of these very basic usability fixes. Fix the focus. Put a text file mapping keystroke events to events in the editor in (wouldn't worry about making the menus display them yet). Actually try writing some programs in the thing.
There are some terrific things here. The debugger is okay within its limitations. The help and information stuff is nice. But the downsides are so bad it's worse than useless.
