I'm sorry for a late reply. I've had to find the old code and re-test it.

Ideally something like this should be the solution:

.note-list > .list-item-container {
	height: auto !important;
	line-height: 1.5 !important;
	min-height: 32px !important;
}
.note-list > .list-item-container > a {
	padding-bottom: 7px !important;
	padding-right: 16px !important;
	padding-top: 7px !important;
	white-space: normal !important;
	word-break: break-word !important;
}

It wraps and displays note titles in whole. However, the problem is that doing so causes weird problems with scrolling the note list. With some notebooks it works, but when there are a lot of notes with their text wrapped, the scrollbar simply gets stuck in the middle, and you're unable to scroll the note list down at some point :confused:.

Because of the above, the "final approach" was to limit the number of displayed lines to two or three as below.

.note-list > .list-item-container {
	height: auto !important;
	line-height: 1.5 !important;
	max-height: 50px !important;
	min-height: 32px !important;
}
.note-list > .list-item-container > a {
	padding-bottom: 7px !important;
	padding-right: 16px !important;
	padding-top: 7px !important;
	white-space: normal !important;
	word-break: break-word !important;
}
.note-list > .list-item-container > a > span:first-child {
	height: 100% !important;
	overflow: hidden !important;
	text-overflow: ellipsis !important;
}

This limits the number of lines to two which is calculated by adding the font size with 1.5 line height (12px + 6px = 18px) and padding (7px + 7x = 14px), and then the second line (12px + 6px = 18px), leading to min-height: 32px and max-height: 50px. If you wanted to show more lines, then the code would be max-height: 68px for three lines, and so on.

This method seems to work fine for most notebooks, but for some I did experience the last item not being shown unless you used the arrow down key to move the note list to the very bottom, which would eventually reveal the last note. The main problem for me was that I didn't even know that the last note was there before doing the arrow down scroll, hence I stopped using it.
