I like that my colleagues can see how much work i am performing in each project without asking me directly or interrupting our meetings/tasks during working hours! It's very good for tracking tasks & deadlines of projects we're currently handling but not yet finished - great tool when used alongside other tools such us Jira / Trello etc (ease-of use). There isn’s anything really bad regarding this software either – everything works fine if one knows exactly why he needs something specific from his client side instead using all these features would be too complicated anyway :) If someone wants an easy way solving business problems while being organized enough there shouldn´n'be any better solution than "TACK".
