at now, the support manager and the order plugin hasn't a events . you should request from Blesta to add events to support manager plugin and order plugin,i believe we have already requested this, as they are the most used plugins in Blesta .
But if this will not happen soon from Blesta team, maybe we will look to this to see what we can do in this subject .
In the first release it will only support browsers notification .
for mobiles, we are working in a hybrid application for mobiles, once finished we will upload it to google store and apple store, it has no relation with this plugin, it will have it own licensing system and price .
