INSERT NULL in data grid in menu and toolbar

We can insert NULL by Ctrl+Shift+N but it really should be on the main toolbar and in the menu.

You cannot have everything in main toolbar. And a button for inserting NULLs should never be in main toolbar imho as it is relevant for Data grids only. Its current location (in context menu as well as on Ctrl+Shift+N hot key) is perfect.

Ctr+Shit+N uses two hands, one i use for mouse. Ok, main toolbar is not right place, but it should be at list on cell edit window, just button (NULL). Or on context menu.

It is in context menu at this moment. RMB (right mouse button) click over cell where you'd like to insert null and then choose 'Insert value | NULL'

Thx, I did not see. :(
