In general I also don't have enthusiastic thoughts about beta apps but I've found the LW 4 betas to be very good. I made a small error about the pause upld. This is present in the jum build for osx only (not the official beta.) Individual pauses would be very good & I thought about inquiring about it myself.
I never use clear inactive button. And prefered to manually delete the completed files but recently set my prefs for auto-clear. You do know how to manually delete them?

Well as far as other p2p apps doing constant requeries, LW did have this function & removed it for the health of the network. Unfortunately there's other apps that simply don't care. Just b/c somebody has a gun & can shoot people down doesn't mean everybody should also have one & do the same. What type of community would that be. They are "aggressive" apps in more ways than just this. I'll leave the others to fill you in about this. The p2p community is developing, but some apps prefer to remain uncivilised & not very communal for 'sharing'.
