The backpack allows me to copy blocks between projects but the contents disappears when I close the project. I was after something more permanent, my current solution follows.
Can anyone point me to an alternative mechanism.
Prerequisite
create a page "blocks" in notepad with three columns
Save a block as a "snippet" in onenote
right click block in app inventer
Download block as png
rename the blocks.png file to something meaningful, i.e. block_timer.png
click and drag the file to a new cell in onenote - this drops the image into the cell
click on the adjacent cell in onenote to select it
select Attach file and select block_timer.png
add a comment in the next adjacent cell
I end up with the image from the png in one cell and the file for that image in the adjacent cell and a description in the next adjacent cell
I can then click drag and drop the file from one note into any project opened at blocks and the copied block appears.
