I like that it is open source software which makes development easy as well as support from community if needed too! It's not so much about its features but more of ease in using this tool compared with other tools available out there such as Crayola etc., So far nothing really bad i can say here regarding micoways product or services provided by them apart form few minor issues they are solving currently (which will be addressed soon). If you want something very stable then go ahead otherwiseβ¦
