Clear Inactive back button

I can not remember how many times I have accidentally hit the clear inactive button and have lost the searches I had pain stakenly saught to find of tracks and artists, too many to remember. However I would like to see a back button on this feature or as in other programs a undo button within the edit box.

Please, please, please. You just do not know how much it hurts to see one loose all those searches, just vanish and there is nothing that one can do about it. Its takes allot of work to prefetch the artists and tracks before entering them into limewire for a possible match to come up in sharing them. Sometimes it takes forever to get a match, but with patience sooner or later it will come up. So when you wait so long, and accidently hit the clear inactive button, all you want to do is kiick youself in the butt or do what I am doing now, asking for an extra feature or change.
