It would be nice if there was a way to delete ALL ended items, instead of having to do one at a time. Maybe there is a way to do and I'm just not aware of it.

If you are talking about Windows software, you can select multiple items and click "Delete". That way you can delete several items at one shot.

If you are talking about Web-based interface, then I'll add a button on the bottom right side "X Ended" later today.

I'm usind the Windows software. Okay, I can now see that you can highlight several items and then delete them all at once. It can be a little tricky to highlight only the items that you want to delete though. A "Delete Ended Items" button to click on would be more convenient, if possible. Thanks.

I'll add a button to make it easier.

Selecting several items is done using standard Windows shortcuts:
Hold "Ctrl" when you need to select individual items.
If you need to select a range, then click on the first one, hold "Shift" button and click on the last one.

Additionally, you can click and drag to select a range as well. This is not a Windows-style, but many people find it useful.

Thanks for your suggestion anyway, I'll add a button.
