Undo last import: enhancement suggestions

Hi,

A few small enhancement suggestions regarding the flashcard "undo last import":

• AFAIK you can undo not just the last import, but previous imports as well (I'm not sure how far back you can go). Consider renaming the functionality to "undo previous imports" or something similar. Or...
• ...consider updating the functionality to undo only the last import.
• If the current functionality is retained (i.e., you can undo previous imports, not just the last one), consider:
  • Instead of a pop-up which displays the date/time of the last import, display a list of X previous imports, their dates/times, etc., and allow the user to select which one to undo.
  • If you retain the current pop-up dialogue, consider changing the message and/or making it more obvious to the end user that they are not undoing the last important, but one previous to it.

I'm making these suggestions because I accidentally undid not just my last import (which I wanted to do, as the flashcard file had some errors in it), but the one before it, which I had imported several weeks earlier. Pleco does of course display the date/time of the import, but its easy to overlook, especially when you are importing/re-importing a new flashcard file multiple times (i.e., you notice errors in the file, you undo the last import, fix the errors, re-import, etc. etc.)

Thanks!

Out-of-order undo of imports isn't something that we're currently able to support, but indicating that this is not the most recent import they're undoing would make sense, yes.
