I'm running 0.9.25C and have a few gripes about data entry into the grid. These are not fatal, but every time I hit one, I'm reminded that this is not yet commercial-duty software. In no particular order:
1) When caps lock is on and I begin entering data into a blank cell, the first letter is converted to lower case. llIKE THIS. Backspacing and retyping lets me get the all-caps I want. At first I thought this was an over-enthusiastic auto-capitalizer, but there is no corresponding auto-uppercasing of data entered in all lower case.
2) Pushing F2 to edit a highlighted cell puts the cursor in a random place. Actually, I think it's the place it was in the last cell edited. Putting the cursor all the way to one end or the other every time would be much better.
3) Clicking on text in a cell inconsistently either highlights the cell or enters text-editing mode.
