Currently the part search panel only allows for up to 50 parts to be displayed. It would be nice if there was no limit. The current implementation however is increasingly slower with increasing part counts. It also generates a fair amount of garbage when updating results (from searching or scrolling). In order to allow higher part counts as well as to improve performance, we need to investigate a scroll panel implementation that relies on pooling and virtual scrolling, only creating and using UI elements that are actually visible.
Increasing the number of search results would come in handy to hide or show a larger number of parts at once.
