I really hope they stick to flash, for custom UI creation.
It's really easy to use & hopefully wont drain much of the memory.

If modders (UI modders / designers) gets a proper Flash-based UI-Mod /creation tool
it will help alot, and trust me...there's alot of of Players with UI/Mod skills around.

Myself included.

I've made a few concepts already based upon the 2.0 UI,
but dont really feel like showing them off just yet.
They're still in a "In Progress" state, and the
design isnt very much to my liking yet.

Been playing alot lately trying to rank up a few classes,
but when im done with that i'll get right back on my concepts again.

Not to show-off really, but to inspire others and hopefully
the Dev.Team to take the UI-Modding seriously.
