Custom order of terms for custom taxonomy in admin and website

I have a custom taxonomy registered for my custom post type. I need to make it possible for a user to specify the order in which the taxonomy terms should appear (something like menu order for pages). Then when displaying the taxonomy terms on the site I will use the specified custom order to order them.

What is the best way to do it? Is there any plugin for it?

Many thanks,
Dasha

Still looking myself.

After some exploring I decided to use the Term Menu Order plugin by @jameslafferty. This will add menu_order to the terms table and can be used across taxonomies and templates. @TheDeadMedic seems to have enhanced this functionality over here, discussing a similar issue.
