whitelist bug

since a year I have problems with the whitelist.. and never got a answer in the other github therad now I'll try it here..
I know there is no development ongoing so well does someone has a fixed version of it?

The Whitelist, Whitelists all websites when I just press Space on time in the input.. after I used the Input I cannot clear the list.. it sets a invisible space in it.. well and if I try to set * behind a website so it can go trough all links with.. lets say Pinterest..
Pinterest.com/"skjdhfksjdf" I don't want to whitelist every picture I want to see?

Is there a Solution to this broken whitelist?

If you have problem with reading my sentences please say it, i try to rewrite them
