Whenever I want to insert a Line break in any description (of a movie, of a collection, of a playlist,…), once the change has been saved, the result is as if two Line breaks were inserted instead. Put simply, the Line break works, but the space between the lines appears double what it should be [see pictures] and this is really annoying…
Plex is treating those line breaks as new paragraphs and Plex Web will draw those with the extra margin/padding you’ve mentioned. That’s normal (no issue related to your particular setup). IIRC there was an argument some years ago when some users asked for something like this while others disliked it… personally I’m neither a Superman nor super bothered.
What a weird thing… If the Line Break were treated as such, to obtain the “Paragraph effect” it would be enough to press [Enter] twice and thus both results could be obtained. In this way, instead, you end up forced to create a new Paragraph while the simple Line Break has become IMPOSSIBLE. Mah!
Sure, it’s not a matter of life and death, but I sincerely hope they will want to rethink or find an alternative solution to allow for both choices…
