Optional Compatibility

I kind of hate to make a request for this after all the work to get that section added but:

It would be very useful if the bottom Compatibility textbox kept it's contents until the Optional Compatibility checkbox is cleared. The behaviour now is that the checkbox is not cleared after Update but the contents are cleared. Did a set with many items that had two compatibilities to set so it would have been very nice not to populate that textbox every time.

This is really easy to do I'll fix it in the next update.

Thanks!
