You can use CSS for that. Like for ...
text-overflow: ellipsis !important;
max-width: 50ch;
white-space: nowrap;
overflow: hidden;
Apply it on title class of that . And add border-bottom below to it
You need to select the limit of char according to your need
I tried working on this as well, but it looks like there are different id=identifying posts. I will continue to try to see if this is possible, but I too am curious if anyone was able to add some extra custom to this. A bar to seperate them would look nice.
However:
1. I only wanted the one line for the thread title and not the thread date but cannot seem to find the title class for it.
2. I wanted the "..." to be included in the thread title and is clickable as well.
3. I wanted the border line to go under the avatar too and not cut off just before.
4. I did not want the line to show under the 5th latest post.
