Quick & Easy but Limited

I have been using this app almost daily for about 4 months, and it works well, but there are things I think it could do better:
First, by using the entire screen on my MacBook Air 11 inch, it is hard to find any text amidst a long journal entry. Even if I have moved the cursor to make a correction, I struggle to find it after Ive made the correction.
The single spacing makes finding text even harder. I wish I could set a format that double spaced or allowed other options to make text easier to navigate.
While I have selected "AutoSave" in the Preferences, it doesnt.
Searching entries is a simple search on keywords and is, therefore, very limited and makes it hard to really find anything. It would be nice if there were categories or topics that could be searched rather than just searching on specific words.
The app lets you give a title to a journal, but not to any particular entry within the journal. Often, I would like to give an entry a title because I use my journal entries to capture ideas and thoughts for my more formal writing and publishing, but being able to search notes only by date or words within the text makes old entries extremely difficult to find.
Even though I have complained aabout several things, I do pretty much like this app and continue to use it. I hope that the publisher will consider some of my comments and perhaps upgrade the app to perform a few more of the functions I have mentioned.
