As a relatively infrequent user of Wikipedia I have only 72 pages on my watchlist and most of them are very low traffic. At this moment in time the default for "Period of time to display" of 3 days only shows 2 edits. There are weeks where I don't check my watchlist at all and it's makes sense for my use-case to set "Period of time to display" to 30 days (that setting shows 10 edits).
Unfortunately, the page doesn't remember the setting and every time I reload the page it goes back to 3 days. I would appreciate it if Wikipedia could save the information via cookie or even server-side.
