Describe the feature you’d like
To have the possibility of set an “evolution of a performer”, and then allow filtering, search, etc. by that “evolution”.
For instance, a performer can be Natural tits at the beginning of the career. Then after few years operate tits and become fake, then after few years get some kilos and become chubby, then…
Describe the benefits this would bring to existing users
Organize better the collection and the possibility to filter scenes by the Prime time of the perfomers, for instance.
Is there an existing way to achieve this goal?
I have implemented all the function in a local copy of the latest code in github. It allows to set the evolution, add an image for each evolution, and then search the scenes based on that evolution date. When you open the scene, the performer image shows the photo associated to that evolution, if any.
The system works with tags so it can be shared between multiple Performers. For instance can create a tag called Prime and then for each performer set a time range for the “Prime” tag. When I search the scenes by tag Prime, it will show the scenes that its date is between the date range of the performers of the scene for the tag Prime, if it has it.
Additional context
I called the function Performer Evolution but sure we can find better name 
So my question is, do you consider this function useful? and how I can send my changes to integrate in the main branch in the future? It’s my first time contributing to stash project.
