I am CONSTANTLY hitting data load editor by mistake, because it is in the place where the Previous Sheet < button should be.
I suggest that the Prepare (Data Load Editor) be moved elsewhere and replaced with the "<" (Previous Sheet) button, and the "Narrate Storytelling" be removed and replaced with the ">" (next sheet) button. The buttons should be enlarged to match the current size of "Prepare (Data Load Editor)" and "Narrate Storytelling", with the names of the previous sheet and next sheet", when screen size permits.
The current < and > buttons are too small and hard to click.
Sheet navigation is really a core function, I don't understand why it is relegated to the far corner of the application with buttons so very much smaller.
This is especially true when you consider user access to the app, most users are not developers and have limited use case for the buttons which are front and center in the app (Analyze Sheet and Narrate Storytelling), and the buttons they use the most frequently are the sheet navigation, and then to a lesser extent bookmarks.
Data Load editor is where previous sheet button should be.
