Every time I fill in a value, the focus is lost and I have to click again to continue filling in.

@AnnulusGames The cause seems to be the PropertyListView class.

This bug is troubling me too. I’ve been writing things in Notepad and copying and pasting them, but it's not ideal. I hope this will be fixed.

It seems Unity changed something with ListView but I haven't found anything from their changelog so I tried to fix it by every time I enter a value I will focus back on the last element I was editing. Another problem while I fixed it this stupid way is that the focus doesn't move the cursor to the end but instead it selects the entire content and so again I have to add a RightArrow button press action to focus at the end so I can continue entering content. I don't think this is a good way but I haven't found a solution yet or wait for a fix from Unity if there is one
