If you're running windows and don't know what a Task Switcher is, try hitting ALT+TAB. Ugly ain't it? I made a nicer one ^.^ Been using it for a year or two.
As for the listview searcher, check out Windows Explorer. That part with all the rows and columns, that's a listview. There's also one in Utorrent. I got really sick of having to hunt for stuff, so a made a lil thing to search it. You just hit a hotkey, type something, hit enter, and it goes to that item in the listview. You can sperate different parts of your search with a space. For example, if I search for "passi dvd_2" in my Utorrent, it will find "LA_FAMILLE_PASSIFLORE_S3_DVD_2.ISO" and select it.
You can also configure the hotkeys for this by right clicking on it's icon in the tray and selecting "settings". Give it a shot ^^ I hope you guys like.
