Root of verbs in vocabulary section

Hi everyone.

I was thinking if adding the root of a verb ,for example kaku/kakimasu ecc,could be an idea,
i mean,sometimes the root form is particular,like with suimasu/suikomu so it's not always
easy to find it.Maybe adding it with a small popup when staying with mouse over a verb for more
than a couple of seconds could be good (to avoid changing the page style with another column ecc)
