everything about the app is way more polished than I expected it to be. Awesome work, Michael and your entire team!

In addition to all the suggestions made by other folks here, I would only like to add and get your feedback on a few more things.
1. Would you be open to adding features like intelligent shape recognition (draw a crude circle and the app replaces it with a clean accurate circle), different types of fills (shading vs. solid fill) etc.? Where I am going with this is, I would like to use Collaboard with my team to be able to quickly mockup wireframes for product design.
I don't expect something as advanced as Invision or Figma, rather, here is a simple open-source tool that my team found quite useful https://excalidraw.com/.

2. The current version of the product seems to have very rudimentary mind-mapping abilities. Basically, the shapes and connectors are manually used to create mindmaps. At some point, would you envision improving the mind-mapping feature-set to support mindmaps that work more intuitively, like with apps like XMind and Mindmiester?

3. Do you plan to build more integrations into third-party productivity tools like ClickUp and Jira? It would be awesome if whiteboarding sessions could easily be embedded into tasks created on these tools, so that teams could capture requirements easily using both tools in conjunction.
