Works beautifully!! Thank you so much!
Some context as to why it's needed:
I'm porting some communities from Reddit and trying to mimic the Reddit titles & URLs.
I increased the thread title length to 300 characters:
https://xenforo.com/community/threa...racter-thread-title-limit.215208/post-1636200 - may also eventually be doable with mazzly's title addon
https://xenforo.com/community/threads/thread-titles-manager.207155
And changed the layout of the titles to be more compact:
https://xenforo.com/community/resources/cxf-customize-row-below-thread-title.6984/
This addon is the 3rd and final piece of the puzzle - reducing the 300-character URLs down to a custom size (70 is nice).
