When all text in a notes field is selected, the cursor and focus are placed at the end of the text. This is especially notable when the text is scrolling due to its length. This is a behaviour which is – as far as I am concerned – unique to Enpass and thus confusing. Plus: there should be either a text selection or a blinking caret - not both.
Having all text selected, pressing of the cursor up key should place the caret at the beginning of the text, just like cursor left does. Instead, the caret is placed in the line directly above the end of the text.
