A few years back my current company created an export plugin on Premiere Elements 7 that brings up its own complex UI for creating video content for our Simulation Product. We have a need to move forward to the latest version of Premiere Element which is now 11. And it seems that somewhere around 9 the export went away and has been replaced with the Share window. From what I can gather you can create export plugins for the share window, but you provide a set of parameters to Premiere which it then uses to build a UI. This is not going to work for our particular application, is there a way to migrate our existing plugin to the new SDK that we can still launch our own UI?
