wishlist: let files to be included be incorporated in the document (as the...

The possibility to use \input, \include and friends provided with 0.41 is great, but appetite comes with eating. Would be even greater to have an interface to include files for texmaths in the document, so the document can become self consistent (in fact, this can already be done with the preamble).

This could work as follows:

• in the main interface you have a button "texmath files"
• clicking on it opens a window, where you have a file list with each entry with an "X" (to remove it) and a "📁" (to re-upload it). You also have a "+" (to add new files). Initially the list is empty (or it could include the preamble as a special file).
• when you run latex on an equation the files are expanded to the temporary directory where TeXMath works just as the preamble, so TeXMaths can find them.
