I've been super busy last night and today. Just now getting back to this. Rather than upload the images I mentioned I could get, I realized I should do some checking around. There was an update to the theme that I use upon updating to Atom 1.17.
So likely it was this update, not the Atom update, that made this spacing larger. I went through the theme code, and found a couple of spots I could change some of the spacing myself.
I'm no pro, and I don't think this is a permanent solution. There are some "issues" risen on the theme page that raised spacing and padding in the theme. I should have looked this up before.
But while I'm on the topic, I decided to tinker around in the
styles.less as I've never tried to customize it before. I was able to get some things changed as I expected them to change, looking through some example code (my
styles.less is probably really bad form and coding, but hey, it worked). One thing I didn't get to work is setting the background color of the tree-view.
When I switch to an Atom core UI theme, this kicks into effect, and the custom background color I defined appears in the tree view, but when I switch back to my preferred UI theme, it is deactivated, and the tree view background color defined by the UI theme takes over. Is this expected behavior?
I'd like to know if this is an issue I did raise on the theme repo, or if it is expected. I wouldn't think it is expected, as my definition works with other UI themes. Also not sure if I should start a new discussion post in discussion.
Thank you again for the help and teaching me a bit about how things work.
