1) As you know, we can add cards in a channel like Bookmarks, Notes, Calculation, Task List, Battery Chart. But these are visible only on the desktop app. Once created on desktop app, these are not seen and visible in the mobile app inside the channel.
2) Notes Card created in a channel are NOT "searchable". I can't find a Note card of a channel by searching the title or content of the respective Note Card. Please fix this.
3) Adding Notes Card per channel is limited to 5. It's a humble request to please increase this limit.
I am a student using Clickup. I have am a power user too. I mostly do not use Lists and Docs (As views) for my work. I prefer creating chat channels instead. I rely on them. I hope you don't suggest alternate fixes but get these done instead.
