1. If you copied from another table, it should paste as a table. If you copied a bunch of delimited text, then yes, it'll paste into a single column and you can you the Split Selected Cells Horizontally command to separate it into columns.

2. That first bug is known and for reasons I don't recall, is much trickier than one would think. It's still on my to-do list. The thing with dragging and selecting everything sounds like it might be scrolling really fast.

3. I'll consider it. Perhaps a smart paste option where it attempts to determine the nature of the text (e.g. whether it's a database table or what kind of delimiter it uses) and pastes accordingly.

4. I'll give this some thought as well. I'm not sure that disabling the commands is the way to go if the user doesn't know why they're disabled.

5. If you have any more questions, feel free to ask. Also, if you do buy and change your mind, just let me know and I'll issue a refund right away.
