The ability of adding multiple tasks with different sub-tasks in one go was really helpful for me while working as an admin/manager at my previous workplace! I dislike its inability not only from UI perspective but also because it lacks some customizations which may be available after buying Pro version!! But there's nothing much wrong apart that since this has been bought by us (as customer) we have started exploring few more features like creating groups etc so hopefully they might add those soon too :) Highly recommended if you're using Action Management software then surely take advantage off these awesome tools provided here:-1). Easy creation & management2.). Customization3.) Grouping4).[Email Alerts]. It comes along great help especially during times where our clients need constant updates about their projects / task status5!).
