It has been wonderful integrating with Pulsar which helped us achieve automated scheduling across multiple departments (salesforce).
We are trying new features from time to time but as an enterprise product sometimes it takes some effort getting those implemented smoothly if at all possible! I have not found anything specific dislike so far about widget brain but there might be something i missed out or they will fix soon though we use their latest version 1 month back atleast :) Highly recommend this tool! Their support team always answer your questions very quickly without taking too much amount off credits etc!! I like how easy it was to set up my schedule (even though this could be improved). It does not have any training or tutorials which can sometimes make things difficult when you are first starting out using an application such as these types - but once again there should maybe more help guides available online so people don't get stuck! The ability to create multiple shifts per day/week etc without having too many options makes scheduling easier than other applications we've used previously.
