It seems to be the case that every element/field of every record can be edited except "Type." Can this be changed so that this element/field can also be edited (perhaps through a pull down menu like used for "Group." As it stands now, if you decide sometime after you create a record as a "Login" (for example) you decide that it makes more sense for it to be an "Email Account" you have to delete the entire record and start all over.

Start with mSecure4.  Create a record of type unassigned ( or 100 records if you have been using it for 2 years), then buy mSecure5 and transfer your data.  Now you have to go in and individually create a new record for every unassigned record.  Very painful.  If you really had that many to change, and  if you still have your mSecure4, you go change them in that tool, then retransfer to mSecure 5.  But if you have deleted your mSecure4,  it is less painful (still not easy) to export to CSV, change them and reimport.  In mSecure4, you could change the record type on the record edit screen.  

But you are right - if you start with mSecure5, it will not let you create a new unassigned record.  But for you, try this .... create a record of type CreditCard.  Now change your mind and switch it to type BankAccount - no can do.    Now imagine you had 100 of those to change and you will start to understand the frustration that many of us have.
