Yes, I was planning to increase the number of available unused addresses
to 10 or 20 in the bip32 version of Electrum.

Related to this, here is another idea I would like to submit:

Instead of using a "gap limit" (maximal number of consecutive unused
addresses), I think we should get rid of the topology, and simply count
the number of unused addresses since the beginning of the sequence.
Indeed, the topology of the sequence of addresses is of no interest to
the user. Users often misinterpret "gap limit" as the "number of unused
addresses available", so I think we should just give them what they want
:) This is easier to understand, and it makes things more predictable,
because the wallet will always display the same number of unused
addresses (except when it is waiting for confirmations).
