Glad to hear you like the improvements!
Is agenda oriented towards a more complete text editing app?
In short, probably not, we don’t have the intention to make it into a word processor that could fully replace Word or Pages. If you are thinking about writing essays, reports, and novels etc you are probably better off to stick with something more dedicated like the before mentioned two, or something more specific like Ulysses, Manuscripts or Scrivener. Agenda’s focus is on note-taking and trying to replicate all the features needed to turn it into that kind of word processor would bloat a great note-taking experience while probably still not being enough to fully replace Word or the others.
Now that’s not to say we don’t want to further improve the text editing experience of Agenda of course. A couple of things come to mind:
making it easier to format text (there are keyboard shortcuts btw for super and subscript), like the recently added improvements to the keyboard bar on iOS and a similar upcoming improvement of the gutter popover that is planned for mac.
offer more text formatting options like the block quotes, text highlighting, etc mentioned in The features we are working on right now…, but also longer term the abilities to choose a theme with different font style etc.
improving the performance of Agenda so it can better handle longer notes and projects
I guess this will already bring it much further on the path you’re asking for, whether it will be enough to turn Agenda into doubling as a tool to create big and serious documents we’ll have to see, as the definition of big and serious is different for everyone of course.
Hope that helps!
