1:I use the win key to open the start menu every day, so I will not click the "start button". In addition, win1-win0 on the keyboard corresponds to 10 applications on the taskbar, so the "start button" is redundant for me. Tried to replace it with a transparent image, but it still takes place, it looks ugly, I need a function to turn off the "start button".

2:The "recommended items" area is useless to me, I hope a future version will feature the ability to turn it off

If you don't use the enhanced Start menu provided by StartAllBack, you won't be able to disable the recommended section. ExplorerPatcher can do this, but it is fully incompatible with StartAllBack.
