Custom Code Modifications

Hello,

We have done some custom modifications to this plugin and we would like to know if do you have a way to avoid that our changes get affected by updates?

For example, we have changed:

1) Capability of videos can be seen, now shows blocks with a thumbnail
2) Video open in the same window with a javascript pop up
3) Description appears when you put your mouse on top of the video
4) Dashboard was changed as well, we included links to membership pro options.

Thank you.
