@BluRae I'm just in my second season of cucumbers, but what I did when my first cucumber was much further along than the rest was to just make a regular sized batch of pickling liquid and now I just keep adding cucumbers as they get big enough.

@afterefx I found https://www.wishlistr.com/ a couple of years ago. I don't know if it's maintained but it keeps working at least and has the features you wanted.
