These two feature are at the top of my most wanted listed for Android:
- The highlighting feature should remember what note file you last selected. Every time I highlight (which I do a lot) I have to search for my note file.
- Easy access to a dictionary definition
- I frequently need to look up a definition of a word and the quickest way now is to highlight the word and do a "word study". The definition should appear when you highlight a word - similar to Kindle.
