Filter function after the text search

One function keeps giving our users a hard time: Namely, the filter function after the text search. 1) It is simply not found behind "Object type". 2) The selection is also not optimal (deactivate "not desired" instead of activating "desired" -> e.g. only process graphics). Is it not possible to make this more user-friendly and visible? It would be even better if only the process graphics were listed in the text search, separately from the connectors, process steps, areas etc. (Possibly a separate tab?) This would mean that there would be no need to filter for process graphics.
