When i go to contact lists, enter a search to find lists it works great, but if i click on a list and go back then i have to enter search information again.
Similarly, if is choose to view 50 items, the find the list i am looking for an click to go back i have to recheck the '50' items.
This adds a LOT of searching, selecting to a simple task that is completely unnecessary. I have my own saas platform and storing current state for each page with regards to search and filtering has improved my users experience enormously.
