aescripts + aeplugins

I perform a lot of Slow Mo / Speed Ramping in After Effects. As seems no way in Premiere Pro to progressively speed up / slow down Audio with Video. 

I can't seem to find any Plugins which speed up the process of time remapping (if anybody does know, please respond below!), so wondered if anyone would be willing to work on simple panel, where I can select an in / out point for speed / slow-mo on timeline, set a preferred speed and it would automatically create a nice eased speed graph between those points and extend the composition for slow-mo (or reduce it for speeding up). 

I'm sick of doing this time remapping by hand and want the quickest way possible couple of click way of doing it.
