Advanced Search Improvements

In advanced search, once you add custom fields, there is currently no way to get rid of them.
For e.g. lets say I did an advanced search and added a filter-more-dependencies. It will show dependencies with “Blocked” being auto-selected. Now if I wanted to edit my search but remove this folder (and many other filters) there is now way i can remove it and i need to restart my search from scratch and re-enter all variables. This can be quite frustrating and would love to see if there is a simple button to remove a filter.
