Been playing quite a bit of this recently and really enjoyed it, and with the poll was thinking what changes I'd want to see, but then realised I could get what I wanted by tweaking things myself so thought I'd share this with others.
For me I like seeing girls advancing through the stages and building up their stats- but many of the girl packs don't allow this. They're either too expensive and so I can't afford them until late game, by which time I've become attached to the earlier girls and am following them, or they've got 100s across the board and there's nothing I can do to improve them. To allow me access to the girls I want early and to build their skills I've actually written a quick Python script (attached in .zip format, wouldn't allow me to upload the .py itself) to let me control the minimum/maximum limits for girl costs and skills.
It's not that I'm complaining about the pack authors here, I appreciate the effort that went into building the packs, it's just that I personally prefer a different playstyle.
If you want to try this yourself firstly make sure you have backups of the girlpacks, I am a professional programmer and this isn't complex code but I'm not taking responsibility for deleting your girls, breaking your PC, or setting your cat on fire.
You then put the limit_girl_stats.py script in your 'girlpacks' directory and open it with a text editor to set the limits you want, it should be fairly easy to see how even if you're not a programmer, max_money =300 is setting the maximum money price for a girl for example, min_posing=50 would mean every girl has at least 50 skill in Posing. The default settings are how I'm currently playing it- $300 max price so I can buy any girl as my starter, no additional prices or lottery, and zero skills.
With Python 3 installed you now run the script and it goes through the folder and edits all Description.json files to apply the limits you've set. If all has gone well you should now be able to open the game and enjoy the rebalanced (some may say unbalanced..) gameplay that you've configured. I did have to fix a small error in one of the girlpacks Description.json manually as it wasn't properly formed (It ended with a comma, that's valid in Javascript but not JSON) but every other girl worked fine- and that's with pretty much all packs installed.
Quick hint though- don't raise min_money above 300, you only start with $300 and you need to be able to buy a girl with it.
