Now, we can see all the categories on the map or only one category (and the list according to it).
It will be nice to have the option to see 2 or more categories at the same time.
Add a new line with chekbox below the 'Show hotspots from all categories' : 'Show hotspots from all SELECTED (see icons below) categories' and filter according to the selection.
Or add a checkbox near the icon (like the small x on the upper right corner we can use now) and filter according to the selection.
Best regards.
