I'm a Trello free user hence have 1 Powerup; there are a couple that look interesting but I can't find any info on whether I get one and only one final choice or whether there's some kind of trial period. What if I select Powerup A and it turns out I don't like it? Can I uninstall A and try out B instead? If I had 2 Powerups I could take a gamble with 1 but don't want to take a gamble with "my one and only coin".
Feedback to Atlassian: having only 1 Powerup without any info on this has stopped me from trying Powerups in the past 3 months I've been using Trello. If you make it clear that people can try things out or at least give them a couple of Powerups you'd probably find more people experimenting and hence getting more value from your product.
