Looks cool, but I can't see for example where I can start to create a custom plugin.. For a basic example some pm2 integration ? Or even something super convenient (for me at least), a WeeChat module that could be present in as 1 widget while I do other things.. Or I'm missing the point of this entirely ? Just to keep it simple : Can I pipe an std to a 'placeholder' widget ?
