I am building a productivity saas for workflow, what features do you want most !?

Hey guys, I started with this idea to embed browser tabs into a canvas tool, so that u can use Notion inside a Miro-like app. I later figured if I can put almost every tool(web saas) into a workspace, and make cross-app experience more smooth. For example, u may be able to drag and drop a thread from Slack to Notion to create a TODO. What do u think? What is hurting the productivity of your or your team's workflow? leave comments below.
