The day has finally arrived, and integrated ads are now part of the free online HeroMachine 2.5 application. I rearranged the controls to fit it in, trying to strike a balance between keeping the maximum amount of space for the character view, and keeping the controls usable. I hope it's not too distracting. The powers that be at UGO are keeping an eye on things, and I'll be happy to pass along your impressions and feedback on the change.
The Desktop Edition remains the same, with the old-style no-ad interface.
