Tracks: featured images dimensions and sticky posts

I found an entry with a similar topic. In the reply it was stated that “In a future update for Tracks, there will be an option to use an image’s natural dimensions instead of a set aspect ratio.”

Has this problem be solved. I recently purchased Tracks Pro and also would like to keep the original dimensions of the feaured images on my blog.

Moreover, is there any way to include sticky posts on the blog page?

Any support is very much appreciated. Thanks a lot!
