In all of 23, when resizing text using the dot to manually resize, when you save and reload the smart notebook, the sizes are not what they were set at. You have to choose the font size using the numerical format in the menu to set it and it not to resize randomly. This is really frustrating, and was not an issue in previous versions. This was really useful to be able to resize using the dot as you could make the text the size you needed by dragging and resizing, not having to choose font size options
