The best feature I like about this tool it's that you can see all your requirements in one place so there are no problems to solve when creating new requirement specifications or adding them as comments for existing ones. It also has some very nice filters which makes searching easier. There isn't anything really bad but sometimes having too much information at once might be annoying if using on mobile devices. So make sure you have enough space available before trying out their product! We used almxtool mainly because we were looking into agile software development methods such as Scrumban/Kanbans etc.
