What is the most limiting aspect of #Trello (Free Version)?

I use Trello to organize my internal tasks. I love the simple UI, but there are a few things that come to mind:

1. Reporting! You have to buy something 3rd party to be able to compile reports. I'd imagine this would be much more important with a team
2. Labeling certain tasks, and being able to filter by said label. Having used JIRA in the past at my previous company, this is where "epics" come into play. This could very well be me just not paying attention and learning how to do this sort of thing in Trello, however
3. Clutter. I'd love to have more view control on what gets displayed. I want my default view to be able to hide my Done category from view
4. Detail. Specifically, I have an "In Progress" lane. I'd love to be able to click through to that lane specifically and be able to see not just the card's title, but also the full description and some sort of collapsible comments for each task. Basically, a view where I can zoom in on the active tasks with full detail

All of the above: lack of general usefulness due to inability to organize and view a project
