Set and remember category filters?

Hey,

I was wondering if it’s possible to view/toggle multiple event categories at the same time, instead of filtering to just one.

Also would it be possible to spread the category filter list over several dropdown boxes?

And lastly, I would like the filter settings to remember when someone leaves the site. So that when the person comes back, it’s still on the same filtered categories.

Would all this be possible with wordpress and this plugin or should I look for a completely different solution? If so, what solution would you recommend for the things I want?

Thx for any help!
