I'm at the last stages of this text, and my goal is to insert a footnote inside a user-defined enumerate environment that is in two-column text. The footnote should appear as a red asterisk and the footnote text should span both columns.
In the MWE below, I've managed to get part of the way there. My two-column text works and the footnote spans both columns. The footnote counter behaves as expected (see solution presented here), but it refuses to change to symbols (or letters - I've tried everything I can think of) or colors. In fact, in this MWE, the color of both footnotes is red (the new color); in my actual file, the color of both is blue (the original color). Additionally, the last paragraph of the footnote has something that looks like 1.5 or double spacing - and I can't correct it.
