Seen in telegram groups for pt-BR. Have a set of predefined (regex) find & replace available in the F&R dialog. For example - Remove white space at end of line - Remove end of line (join lines) - other common situations for people that need to reformat content.
+1 But, little room on the Full F&R dialog so would need to provide a pop-out selector button like checkbox dialog for 'Attributes', but applicable only to the 'regex Replacements'.
Perhaps extension material?
(In reply to Eyal Rozenberg from comment #2) > Perhaps extension material? There is an regex F&R extension at https://extensions.libreoffice.org/en/extensions/show/70066 However, this extension is far to complicated for "Joe User" ( =average user) and requires knowledge in regex which is the issue we want to hide here.
