This is just some harmless fun of course, and potentially offers some nice options for Qlik bloggers, for example click to automatically generate an app, online performance analyzer, etc. Just be aware that there could also be more nefarious purposes, for example deleting applications or extracting data. It’s probably very unlikely that someone will target this, but good to keep in mind anyway.
On a different note, Qlik Sense 3.1 SR4 was released yesterday. And, if you’re based in The Netherlands (or willing to travel there) and interested in Qlik Sense web development with mashups, extensions and widgets then we have an interesting training coming up. More info here (in Dutch, but training will be in English, contact me if you’re interested).
