In the ComboBox widget, if "Selectable objects" is set to type "Database" a search is triggered after each character typed into the ComboBox. This can be quite inefficient on big DB tables especially in cases in which the user needs to type multiple characters first to get any meaningful search result. If the user types quickly, multiple DB queries (and xas requests) run in parallel leading to unnecessary DB load and bad performance.
Idea: Introduce a setting "Apply after (ms)" like it's already available for "On change" events on several input widgets (e.g., Text Box, Text Area, ...) in order to not re-trigger the search on each change but only after the specified time has passed.
