LibreWriter styles strange behavior
It could happen that apply a (custom) style doesn’t work as expected, i.g. even you have in that style a margin-left this margin is not applied, or it is only temporarily.

Regex for first lowercase letter
If you have en ebook that split badly a paragraph, you can try (to merge the bad splitted paragraph), as find
</p>\n\n\s\s<p>([a-z])so that a paragraph beginning with a lowercase word be merged with the previous one.
But in Calibre editor you must check “case sensitive”, otherwise [a-z] will be read as [A-Z], and all first letters (lower and upper case) will be selected.
And as replace you could try
\1In this way you keep whatever letter is found with ([a-z]) in the result.
Regex for “space”
It can happen that you want replace a double space before <p>: use the \s. I.g. to replace
,</p>
<p>
You should use this find: ,</p>\n\n\s\s</p>
