Thanks. Actually, my university (UCL) was oferred access to Lucidchart for its students for that project that we did. So it was one of the web-based tools I tried. Looking over the paper I wrote, it seems I actually did happily use it for the domain model, the use case diagram and an early version of the class diagram. However, I think for the sequence diagrams I found it a bit clumsy (for example regarding activation boxes) and eventually gave up. I should note that I think most (probably almost all) of my classmates also happily used Lucidchart, as it was recommended by the lecturer too. But I was a bit overzealous and preferred the more rigorous system of astah, like keeping track of the methods you add to each class and the stricter visual organisation of elements. As for particular examples of UML elements that I wish lucidchart had, I can't really remember, unfortunately.
