Problem:
The current filter panel is a mix of configurations without clear grouping, placed very close together, and difficult to scan; there is no indication of which filters are in effect when the panel is closed; the expanded panel can take up almost half of the screen height without configuration; filter action buttons have vague, non-descriptive labels and no clear visual priority; the filter has lots of unused space

Expected result:
Easy-to-use and easy-to-understand filter setup; users configure the filter based on their needs at the given moment; filter is compact and has clear structure; it's clear what filters are applied now; filter configurations have clear labeling and logical placement
