I dunno, for a Sword style spell cast bar, i always pictured the actual "Gem area" of it to be upon the scabbard with the Sword sticking out at the top.. Perhaps with the sword all the way in when spell book is closed, with an animation of the sword being drawn just enough to reveal a glowing blade or something like that... Im no graphic artist by any means tho, and until now, didnt really have a reason to make such a suggestion... But if anyone wants to undertake such a project, well.. 1- id prolly play my pally more, and 2- id have one helluva mod for em.
That said, Ima major T.King Fan myself, and look forward to seeing some of the new mods in development, let alone using them, ESP the Druid Class animation. :P
And to anyone working on the eq dev team, for the love of god, Hire Thomus already, let his eye candy / programming skills effect more in Everquest than just the UIs.
