I was also disappointed by the lack of utility for the game session feature. Instead of waiting for enhancements there, I created a custom category called "Game Session Summary". It has fields for the in-game date range that the session covered (my game world uses a calendar system that matches the gregorian calendar, so the lack of a custom calendar isn't a problem), the real-world date when the session occurred, a session summary, a list of encounters, a list of loot and other rewards gained, and the experience gained. Most of those are just simple text snippets.
My realm has an event list category called "Game Sessions", and after each session I'll add a session summary topic to it, fill in all the fields, and reveal all the snippets. Since it's a proper topic in RW, the text in the fields will auto-link to other topics in the realm. For the summary, I'll usually just write up a couple paragraphs that cover the key points of what the party did, making sure any relevant things that have their own topics get mentioned to create links. I'll format the encounter and loot snippets as simple bullet-point lists. If there's additional information about that stuff that the PCs don't know (like what unidentified magical items actually are), then I'll add that in GM directions for the snippet so I can refer to it later.
I don't currently use the storyboard/plots feature at all, so this has been a good way for me to track the storyline in a cohesive manner that utilizes all the linkage that RW provides, in a way that's visible to both myself and the players. It isn't perfect, but I think it works fairly well for the way I do things. Sometimes players miss sessions, or just forget potentially important details about what happened in a given session, so it's good to have that information available for them to reference.
