In some parts we select from a check-list with the country codes (eg. US) just like the old version and it's better because the popular choices or our frequently chosen options are listed on the better.

In other parts (eg. in Cohorts) we have a list of alphabetically sorted country names, this is really tedious because you have to scroll down so much to find some countries that are typically among the most frequent selections for most people (eg. United States).

And because the filters are automatically reset after some time of inactivity or upon refreshing the page, one has to do this dozens of times.

It would be good to have the same country picker method everywhere (I think country name instead of country code is easier to read) and one that considers the users frequent decisions eg. lists the ones recently picked in the top of a list.
