Orbweaver replacement

HI, idealistically I am hoping for Orbweavers next generation to have:

1) same ergonomics, its definitely much better than Tartarus
2) scroll wheel is not necessary, I would rather keep that for Tartarus so there are two different devices to choose from
3) extra row of buttons or maybe even better extra column of buttons would be helpful
4) alternative to #3 would be more buttons behind the thumbpad to switch keymaps/profiles, although very handy sometimes hypershift or double actuation is not always the option
5) onboard memory, its a dream but anyway, in some working environment Synapse installation is simply not allowed due to security reasons
