--> I would like to find out whether the Woocommerce Booking plugin is now compatible with Toolset Views. Particularly, is there an option to filter bookable products using Toolset View filters?
That rather depends on how WC Booking stores its data.
Views can filter by taxonomy or by custom fields, including those registered by 3rd parties.
It is not uncommon for 3rd party plugins to store data in hidden fields that you may want to use, but as described in the other thread, you can typically expose such fields in the Toolset settings so that they can be used by Views shortcodes and filters.
This should be fine with simple numeric and text fields. Views won't necessarily understand the format of more complex fields, and will treat them as strings.
