Sir_Ivan Having it open at desired location would certainly be a step forward. But, yes, the way I'm currently using it it would nice to just have it open at all times. And, yes, I'd imagine clicking and then typing to activate....
That being said, its quite possible that my workflows could evolve to the point where I would no longer want it always open. As a new user to premiere (and video editing in general, my background is in pro tools and audio), I'm still learning and designing my workflows. As I get things fine tuned and have shortcuts and macros developed, I imagine I'd be less interested and reliant on using the excalibur search function at all. Hard to say.
Another idea that might be interesting (IDK if its possible with the API) would be to have floating palettes with a list of specific shortcuts/macros one could trigger simply by clicking on the name of the macro in the list...like keyboard maestro. Sometimes there are very specific macros one needs, but not often enough to devote a whole keystroke shortcut to it.
