So, to emphasize what I mean, consider the following example: You want to enter a chemical sum formula (or an whole equation) into a text, spreadsheet, whatever. Of course, you can abuse some of the already existing tools such as superscript/subscript in a word processor or math mode to get the symbols and format you need.
But, one could think of a more natural way to enter such information and I am sure there are already approaches to do so. Also approaches for data file formats to save this information, ...
Now, are there journals dealing with developing of such methods and approaches?
