Hi Ernest!
Thanks for your answer, I applied your changes and now it looks great 😀
The only point I think I did not explain myself well is the background color for the date field before opening date picker itself. I would like to have it with the same dark grey as the tabs above it.
4.- I could ask WP Kraken but…I’d rather pay you as the author of an awesome plugin. So let me know if you would do it and how much would it cost. If you don’t want then I will ask them 🙂
Thanks for all your help!
