“Balance” gets abused a lot, as a term. It means multiple things, and it results in people talking past each other.
Intra-party balance – that is, everyone in the party being approximately equally capable – is important for most tables because most people resent getting clowned on by their so-called allies.
Creature/encounter balance is not about forcing the fights players get into to be fair, but about having a reliable way of telling how hard the fight will be. That knowledge is not an obligation to make the fights fair.





I like Trilium Notes. It’s rich text based, not markdown based, but haas most of the organiation structures of Obsidian. It doesn’t have the user base nor volume of plugin support, though. It does have a canvas mode for inking, but it’s a separate note type, not part or every note.
For a purer inking environment, look at Xournal++. It’s not as feature rich as OneNote, but it has the basics.
Or, you could try running OneNote with WINE. It looks like you’d have to use OneNote 2010 or 2013, though.
