small UI quirk, right arrow / triangle to step through sheets jumping away,
if not all tabs for the sheets in a workbook can be displayed in the bottom row, two little arrows / triangles appear besides the tabs with which you can slide / step through the tabs.
The right one of these arrows sometimes jumps aside for some pixels ( ~2 characters wide ) what is inconvenient when one wants to step through a large number of sheets while keeping his eyes focused on the sheet content.
I think the 'jump away' depends on the cell content of the selected cell(s) on the sheet, if that is a wide numerical value or formatted for display with plenty digits the 'sum' infobox in the right bottom border has overflow and pushes something left?
E.g. if the selected cell on the sheet contains '9' with number format 'general' -> normal position,
in contrast '0' or even the text 'Fail:' in a cell formatted to 'scientific, 20 decimals, min. 2 exponent digits, always show exponent sign' -> arrow pushed left.
The effect seems independent of the setting of the border tabs / infobox, the push also happens when there is plenty of free space between 'sum' field and tabs.
