I want to try to remove the following buttons that I won't use

• 

tried to double click on tool, then UI seems to become editable

• 
• 

then double clicked again for the area Tools sit

• 
• 

then checked script side

• 

I could not find the code for 3 buttons, so tested to remove some languages

• 
• 

then verified the result change, and committed the change

• 
• 

Seeing the effect above, tried to remove the following line, then no changes, so reverted the line.

• 

tried to find the code by string , so chose polygonal that is expected less place to be used, then found the following

• 

then tried to remove them by the following commenting out

• 

and verified the bottons disappeared

• 

then submitted the change

• 

ymd20250316 reverted the pan menu

• because add 3d layer caused the crash without the pan tool
• 
• maybe I will remove pan again with the code change for the 3d layer
