Hi. I am unable to resize the reading panel by either dragging sideways or up/down, or the same for the side panels. It would be ideal if you included dragging handles. Often trying to pick the resizing point is difficult and wastes time. Just noticed that there is a dragging handle at the bottom of the left side panel and it does work but still I cannot drag the right panel or the top part of a document, either in bottom view or side view. Just noticed that if I use the drag handle, it stays selected and I can drag the right pane. If not selected I cannot drag the right pane. And it does not allow the up dragging of the reading window.
While I have you attention. Re: You now can group your custom items in the [Navigate] sidebar, e.g., your favorites, smart rules, etc. Please explain how to use this function since it is not evident.
And last, can you please improve the contrast (or better yet let us modify it) of the “Alternating row color in views”. The highlighted row does not really stand out in dark mode.
