Hello there!
PROBLEM:
I have hundreds of shared files and, when I want to change the share level of some file in the "shared files" list, it is a bit painful to locate it. The same happens in the transfer list (I have a very long queue).
Ordering the list by name does not help, because most often I don't know how the file begins; I only know its name contains the word, say, "clavichord".
This discourages me from setting appropriate priorities for my shared files.
SOLUTION:
There is a very simple elegant solution: add a quick-search box on top of each list, a-la thunderbird. Once you enter a keyword in the box, after 1 second of delay, the list content is narrowed to only show the files whose name contains the keyword.
How about it?
