KnjMokoOPKG is an application to install, remove and search for software through Opkg.
Instead of using Opkg directly (which is horribly slow), it uses knjOPKGDB (which is a SQLite3-database with information about the packages), making it much faster than simular tools.
It is written in PHP-GTK.
How to get it
It can be install through the Knjrepository like this:
opkg install knjmokoopkg
