Describe the feature

Sometimes with my mobile FGO loses frames and as a result FGA can accidentally press the wrong thing, or miss pressing a command. Most of that can't be fixed (unless I buy a new phone), but for the Support selection there is another option. Specifically during scrolling for support, when FGA scrolls through the scrolling can be set to be more to the left. That way instead of FGO freezing and FGA accidentally pressing on the wrong support, the scrolling can be done on the empty space that was added when fullscreen was activated. Obviously since not all Phones have the same width, that could be an added option to activate (like Stop on CE Drop etc)

Just encountered this issue. It appears like FGA when scrolling actually presses on the servant support panels (they are highlighted), so sometimes it can accidentally chose wrong support when the game doesn't detect the "scrolling" action (due to lag for example). FGA should scroll closer to the border.

Don't think this needs to be an option, as it shouldn't be hard to calculate from the game area.
