In Explorer, in the list of process definitions, currently the icons representing the actions are confusing. You need to hoover to see what action you're going to perform.
Either the icons could to be extended so that those images become full buttons. Or the icons could to be changed into simple links with small text and underline. Just make a proposal what you think is best.
I propose as the texts: "Show Start Form" or "Start Instance" and "Show Diagram"
