I'm looking for apps that would meet the following requirements:
1. Clipboard manager that would be able to catch copied data from any other app and then export.
2. Book reader that would have an area or a tab for writing notes
3. Screenshot taking app that would offer to select a portion of the screen
4. App that would enable handwritten inpup in notetaking apps
5. Notataking app that would support japanese language encoding
6. Keyboard for japanese language
Thanks for any advice! It's much appreciated
