In the Join Tables Platform, what's the difference between  Update main table with data from second table and
Merge same name columns?

Update main table with data from second table assumes that the user wants to Merge same name columns.

So, it's kind of a special case of Merge same name columns.

If Merge same name columns is selected, then any selected columns from the Main Table [will be] Updated with data form second table.

So, no Merge same name columns without Updat[ing] main table with data from second table.

The submenus of my Jmp installation always open to the left of the main menu:

Where is the setting to move submenus to the "right"?

add-on question: what is the background of them opening on the wrong side?

[#4]

It has been my experience that if you move the window you are selecting the man menu option too, to the left edge of your monitor screen, JMP will open the submenus to the right 

[#5]

Good point, I hadn't noticed that before.
When moving the Jmp window from the left to the right, there is already a small area on the left of the screen where menus open to the right ☛ (highlighted in blue).
In the remaining area of the screen the windows are opened to the left ☚ (highlighted in red).

Almost seems that as soon as there is enough space on the left - the submenu will flip to the left.

Why do I need a numeric column to add a column with row numbers?

name is Character column -> no "row" menu in the New Column Context menu:

height is numeric -> I can add a row() column

similar questions about ranking Character values, counting non-missing values etc.
