Sri,
1. We do not have this built-in.. however, you may want to check out these plugins:
https://www.philopress.com/products/wc-vendors-maps/
https://codecanyon.net/item/wcvendors-store-filter/19664812?ref=kas5986
2. There is not yet a filter for this; so you can remove this with css. Not ideal.. but this should do it:
li.show_if_booking {
display: none!important;
}3. I am not certain how to work with the deposits and vendors/commission.
I have heard a few requests for this, so I will add it to our enhancement requests for the Bookings integration and see if we can come up with something int he future for deposits.
4. Refunds are handled via the payment processor. Yes- they are manual.
