[WLE] Plug-in Detection

I accidentally added a plug-in to the exclusion list. When I removed it from the list, it still didn’t load. Adding an object appear to take effect immediately, while removing it doesn’t!

I had to resort to a “Force plug-in detection at next launch” (which takes a long time) to make it appear again. Is there any way to manually make WLE detect a single plug-in? If not, please consider this a feature request.
