Notability 4+

When I use Apple Pencil to highlight the information, it perfectly syncs though all my devices. However, when I tab the word or longer sentence and select the content I want (In this case, we don’t have to use Apple Pencil to do this. We can also have an option for Highlighting the words or sentences you want), it sometimes doesn’t sync well though all the devices. Even worse, It’ll crash every time I touch the highlighted area without reasons by using other devises. For example, if I use my iPhone to highlight the information, I cannot use my iPad Pro to tab the highlighted area. And if I do, it’ll crash immediately and relaunch the app again, but the problem is still there. I don’t know what happened to this, but if this function can work as well as using Apple Pencil to highlight and sync perfectly through all the devices, it’ll be great!

The most useful feature for me is the "Image to Ink Conversion," but I believe this functionality can be further enhanced. As a software engineer, this feature helps me convert responses from chatGPT or Bard into editable graphical text. However, some text conversions are a bit challenging, such as imperfect rendering of characters like 'a' and 't.' I suggest incorporating a bit of OCR (Optical Character Recognition) algorithm into the "Image to Ink Conversion" to improve the accuracy, especially in recognizing A to Z ink conversions.

Additionally, I think it would be perfect if there were options to adjust objects, allowing for "Move Up One Level" or "Move Down One Level." This feature would help me alter the display order of two objects, enhancing the overall user experience.

Would be nice if we could have a tool that works like a color fill. Basically, when I have written a text and want to emphasize some part of the text I could do it three ways: 1. highlighter, 2. underline, or 3. I could select that part of the text and change the color.
The problem is, I use three a lot and having always to select, tap style and choose the color is a hassle. I could really use a tool where you just pick one color, and whatever stroke you touch with that tool is going to change into the color that you pick, this way I could easily change some letters, words to the color I want in a fast fashion. In short, I would like an eraser that, instead of erasing strokes, fills in the whole stoke with a specific color. Thanks!
