The ease of use, it is very well organized so that you can quickly find what needs to be done next even if they aren't in your list alphabetically or by category. I like how easy this software makes doing an audit/technical assessment much easier than other tools out there! There are some functions missing from zeva which could make things more user friendly but overall we haven’t been able complain about its shortcomings as long as their customer support team does everything possible with our requests to resolve them ASAP (we're talking minutes). We have used many different forms of assessing clients' websites at various stages throughout my career thus far including using several plugins such as Firebug while building sites before launch; creating content audits through multiple platforms ranging from Google Analytics all the way back when GA was new etc..
