I want you to write a minimalist android e-ink optimized note taking app. What we want:

- The app has a list of notes, they are internally stored in text as ISO timestamp (2001-01-25T20:35:45Z.text) files
- We can choose either a local folder, or sign in with owncloud and choose an own cloud folder to put the notes.
- The note hierarchy is flat
- Notes are pure text, eventually we want to highlight markdown syntax, but there should not even be a render mode
- Monospace font
- Links should be clickable even without markdown syntax
- The app should work offline if owncloud is offline
- We want search
- If the file contains a #hashtag, it is tagged and the tags can be navigated
- * * will mark the words within as bold and _ _ as italic
- if a line starts with -, then going to the next line adds a "- " automatically, if the first key pressed is newline, then the leading "- " is deleted, if the line was indented, the indent is also kept, this is to make list entry easier
- starting with - [ ] creates a checklist, tapping inside the [ ] checks the item, same rules apply for going to the next line
- the list of notes inside in the main view shows the first three lines
- this is not real markdown, just very lightweight syntax
