I tried to post this on Jira, but the server is stalled for some reason, I'll post it there later, but I'd like to keep a copy here too of my idea on this subject.

Not only it should show the Download/Upload ratios, but if you right click on the Limewire, you should have quick access Gauge controls to quickly adjust bandwidth from there, without needing to open Tools, Options, etc.

This I found very useful with eMule Plus.

------------------------------------
|
| Upload ---|------ 10 kb/s
| Download --------|- 9999kb/s
| ( ) Set both to maximum
| ( ) Set both to minimum
____________________________________

You can have several other radio buttons,
in case you let user create what I would call
"Bandwidth Profiles"

( ) I'll be away for a while, Share baby!!
( ) I'm back, Keep it low
( ) I'm here but not browsing much


All this could be available to you, on a Right Click
on the IconTray Lime (XP,Linux with KDE or Gnome), and in the case of us Linux users with not so fancy Window Managers,
that section on the left bottom of the Window, where you put
the green bars, it'd be perfect to show Upload/Download Rates,
and if clicked, show a little dialog like depicted above.
