I share some really rare torrents and need to see the amount of seeds/peers to prioritise which to upload and which ones I can stop without leaving the torrent with no seeds.

Also Limewire has no option for making torrents.

I use Azureus for that and Limewire for single files.

If you have enough bandwidth and RAM then there should be no problem running both at the same time. Just set the allowed bandwidth for both programs accordingly.

With that said Limewire is being worked on always and I'm sure these things will be fixed in time.
