Incremental filtering while user is typing might cause too sluggish
response, so I'm fine with the current non-incremental filtering.

BTW, what I still miss in package filtering is a key to match
package descriptions (in addition to package names).  For example,
Ubuntu package manager allows filtering by these fields:
"Name", "Description and Name".
