I'm assuming this "Discussion" page would be a good place to report bugs as suggested on the Terminal page...
Anyway, when I try to tab-complete a line (Sym + i), the line becomes blank. The cursor stays in place, and the line of text disappears. When I hit enter, it works correctly (only a display issue, not a tab completion issue). I can get a screenshot if that is necessary/help any. Also, the terminal app seems to immensely slow down my Pre after a min or two, and it visibly lags as it closes and minimizes the app, then immediately speeds back up once its closed.
Not complaining, just reporting bugs. Thanks for all the hard work!
