Hello, first of all let me thanks you for the app you build, it's great for my current project. After using it, i noticed if it could be somehow improved. I was struggling with the filter because i need to filter for ex. 20 datetime columns out of 400 or 500 columns parquet files. So i decided to try to improve the selected fields feature. I believe i did a good job. I placed an additional textbox that allows filtering for a single column or a multiple columns using a string.split with commas separated string. This is useful to me for fast select of all columns which can come from a metadata file or something alike. If you find it useful, maybe you can include it with in your repo source files.

If you have any questions please let me know. Just a note, this is my first fork / pull request in Github so please bear with me if i made something wrong.

Agains thanks for the tool. Hope to hear from you. Cheers

I'm adding this to v2.4. Will play around with it a bit there. Hoping to merge it soon.
