Good if the form can employ multi-columns

I received copy of Formoid beta download link from you. I downloaded
it and tried it out. The following are my suggestions:

1. It will very good if the form can employ multi-columns
2. Though simple to use, however we have many extensions that can
offer something as easy as that while still more advance. I recommend
you make provision for advance users to incorporate anything they want
into the form (like javascript etc). In line with this, I suggest you
option to hide fields in the form which will be called on radio button
selected or checkbox checked. Slight advance feature like this
attracts people nowadays.
3. Make it excellent by including calculation feature. Forms as used
by business oriented websites today is not only just to send a message
or notify someone but the profession also enjoys creation of forms
that can fetch data and carry out computation on two or more data and
present results.

Those are what I have for now.
keep the good effort
