Another issue that wasn't mentioned is the search-as-you-type. The problem occurs especially with the Locate32 plugin - FARR sends what you write immediately to all the plugins. While this can be solved on the plugin level, it might be better if FARR didn't "send as you type" but instead give it a few milliseconds for you to finish the search query (or even better, make the delay customizable).
i think there is already a delay, which is not customizable... i already asked for that, IMHO it could be directly in the ini file
i think the real problem is when you search a network drive, where you feel that the search box is linked to the results
when i search for music on my network drive using a dosearch alias, FARR just hangs for seconds (sometimes even showing not responding in the title bar) just after i typed the trigger of my alias (so i cannot continue to type...)
