Proper Search Function
Shaxpir's current search function isn't practical. Yes, you can search and it's pretty cool the way the app highlights the search results inside the document, but you still have to scroll through page after page of material in order to (hopefully) spot the highlighted content.
I've never seen a search that works this way before. Most documents allow you to jump directly to the matching values, but here you don't know [A] if there are any matching values, [B] how many there are, or [C] where in the document they're located.
On a side note, it would be nice to allow you to search across multiple chapters as well, but this would only really apply if the search was updated to jump to the target word/phrase.
