I changed over time from Evernote, to OneNote to notion, to mem.ai but now discovered agenda and love it. For how I use it, it is close to perfect except one key feature missing:
Tag a sentence or paragraph and have an overview of all sentences/paragraphs with this tag and a link to the original note.
These tags can be action, idea’s, person, etc. If you crack how to grab the text in the same line/paragraph and show them all on one page, the use-cases are endless.
Mem.ai does this for tasks only, Sapium does it for all tasks but missing all agenda features which make Agenda so nice and beautiful.
With these examples, can make it? If you give it some thought, you will start to understand this is THE kill feature.
