1. Please allow adding multiple spell-check languages at the same time. Currently, text in other languages is marked as incorrect even though it’s valid.
2. Please add an option to add custom words to the dictionary, so they won’t be flagged as mistakes in the future.
3. When drawing shapes (like straight lines or rectangles), the next stroke often jumps to the bottom of the page. This makes it hard to draw anything that requires more than one line.
4. In text documents it’s possible to insert tables. It would be great if tables could also be added in all other document types.

Currently, the only way option we have is "Enable spellcheck for New Documents". I use this app to take notes in my college courses. I am constantly switching between writing calculus equations and annotating computer science lecture pdfs. The app currently always tries to spellcheck my equations and thinks that they are words. I want to be able to enable spell check for a specific document, or even toggle it for a certain folder (Off for Calculus, on for others).

Please, as on Ipad, spelling check!!
