Undo feature should only reverse 1 command

[hcs1203]

It will be easier to check if the outcome of the command if the undo command only works on one command. It will save steps if the undo command in the example in the video only undid the delete and still showed the filtered step.

Team's Response

We currently implemented the undo feature to show the full list every time it is executed, to accommodate for cases where the undo reverts changes that are not shown in the filtered list.

For instance:

• Start with the same buyers list as in the video
• bdelete 1 - deletes "Alex Yeoh"
• filter John - filters out buyers and sellers with "John" in their name
• undo - undoes the deletion of "Alex Yeoh"

To show the restoration of "Alex Yeoh" in the original list, the undo command displays the original list instead of maintaining the filter.

At the same time, your suggestion is very accurate, and it would definitely be much better if changes to a filtered list when undone, still maintain the filtered view of the list. Perhaps in future iterations of our application, this can be an enhancement to the undo feature, where undo remembers whether a change was made within a filtered list or outside of the filtered list, and shows the appropriate list correspondingly!
