It is worth remembering when considering alternatives that most are not as comprehensive as the original, and are deliberately ‘lightweight’ in design, missing out some of the lesser-used features in order to gain speed in those that are utilized more often.

The nature of the web management industry is such that the availability of alternatives will change on an almost daily basis as users look for newer and better ways of making their lives easier, and their daily tasks less time consuming.
