A conditional for this won't work unfortunately...the trick is to find an alternative script that does equal height columns, otherwise that functionality would need to be removed.
As for a timeline, hard to say because at the moment, I have a heavy workload. For this issue at hand though, it really depends if I can find an alternative script. I tried looking for one last month but still haven't found one that works 100%. This is a very complex function that I tried to implement because I wanted to maintain full responsiveness while achieving equal height columns. For the most part, it works, until something gets added into the content area that needs flexible height expansion.
I will try my best to find something, but it may take a couple weeks before I can do anything for an official update.
