Hi! Long-time lurker and fan, first-time poster. I'm Adam, and I, along with my co-founder Tymon, have been running https://ubots.co/ building Slack apps as a side project since 2020.
We've built and are in the process of releasing our fifth Slack app - https://ubots.co/memo/
Unfortunately, Slack has recently changed its rules to approve new apps to the marketplace and now requires them to be installed in 10 active Slack workspaces before submitting for approval (https://api.slack.com/changelog)
We wanted to take this as an opportunity and ask for your feedback as well - who better to ask than people actually building products.
If you're a member of a Slack workspace and would like to install the app and send us feedback, we'd appreciate it very much! We're extending trials to a month for beta testers and can send you a lifetime discount code if you find this app helpful.
Happy to answer any of your questions, especially about platforms or Slack in particular
