Stylesheets accessible for all MINERVA users - Improved aesthetics
Just an idea.
Maybe could be encoded within the SBML renderer project.
The stylesheets idea: I got it from how we have it in Newt sometime ago. You can switch between styles: http://web.newteditor.org/?URL=http://metabolismregulation.org/downloads/F006-ACLY.sbgn (please see the screenshot attached)
Also, another example: Krayon project uses CSS to store styles https://github.com/wiese42/krayon4sbgn/tree/master/resources/styles/read-only Then the styles appear in the editor. Krayon is a new SBGN editor, I tested, it works nicely, developed by a co-founder of yWorks and now is being managed/improved by Andreas Drager.
The default styles should be really good and probably chosen from existing examples or designed by an artist like it was done, I understand, for the new super-nice blueish MINERVA style.
