There are times when it's really annoying to be typing a search criteria only to have X1 run off and try to search out what has only be half-typed so far. This bogs down the typing immensely, and often freezes the UI entirely for a while, only to waste time banging on the hard disk looking up results that aren't what I really what (because I'm not done typing the search criteria yet).
How about an optional mode (activated/deactivated via "Options", naturally) that stops X1 from initiating a search every time I type a character into the search boxes, and instead waits for me to press a "Go search now" button (which will appear on the UI near the search box when this optional mode is chosen)?
