Currently, the mass blocker requires users of it to manually type in the reason. It would be nice if it could use a dropdown menu like the normal Special:Block form. Ideally, the reasons list should be controlled by something like MediaWiki:IPbreason-dropdown or a separate interface page, with the default being "other reason" (because most CheckUsers are used to typing it in manually).
For those who do many checks a day, this could be a big time-saver.
