3 PRs awaiting merging

[moisesbr-dw]

Please merge my PRs #229, #230 and #231.
All three are minimal and fix bugs found during testing.

I will also review the translations for Esperanto and brazilian portuguese someday.

Thanks!

Translations can been added or modified via the translation tool of DokuWiki at https://translate.dokuwiki.org/

Further interesting improvements, thanks!

#230 still awaits...
I have added screenshots to better show the result of that change.
