I am using the code below to achieve footnotes and footcites at the bottom of the page using the manyfoot package.
Everything that was used for the code can be found here: Biblatex cite with footnote only once, with use of brackets and Biblatex footcite: customizing biblatex and bibliography style and How to cut out a prefix in the doi field if present and Get rid of undesired vertical spacing within single footnotes (and footcites that are displayed at the bottom of the page) due to setspace settings and How to horizontally align text within longer footnotes (and footcites that are displayed at the bottom of the page) that range over several lines

moewe's solution redefining the manyfoot equivalent of @footnotetext enabled nice, uniform spacing within the footnote part at the bottom of the page.
Now I would like to slightly increase the vertical spacing within footnotes (that is a uniform spacing between and within (!) footnotes). Increasing the linespread with \linespread{1.05} does not affect footnotes anymore. Using \setstretch{1.3} of the setspace package does not affect these footnotes as well. moewe suggested to play around with \footnotesep by changing \setlength{\footnotesep}{2\footnotesep}, but this only changes the spacing between the footnotes (and not within footnotes that go across multiple lines).
Example 1: \linespread{1.05} and \setstretch{1.3}
Example 2: \linespread{2.00} and \setstretch{2.0}
Example 3: \linespread{1.05} and \setstretch{1.3} and \setlength{\footnotesep}{2\footnotesep}
How to evenly increase the vertical spacing within these footnotes?
\baselinestretchshould address my problem, but unfortunately changing\baselinestretch {x}leads to non-uniform spacing within the footnotes (try for example\baselinestretch {1.1},\baselinestretch {2}and\baselinestretch {4}) Does it work for you? – Sacharja May 29 '20 at 17:07\baselinestretchin\MFL@fnoteplainand the scale factor of\footnotesep(e.g.\def\baselinestretch {2}&\setlength{\footnotesep}{2\footnotesep}) I get something that looks fairly even (to my - admittedly - very untrained eye, anyway). Of course you can still change the two independently in a fine-tuning process in case you are not entirely happy with the result. Just play with all the values a bit. – moewe May 29 '20 at 17:19\setlength{\footnotesep}{x\footnotesep}. I agree, it looks pretty even. Thanks moewe. – Sacharja May 30 '20 at 08:27
