Unable to Paste in "Add Custom G-code"

I have been playing around with manual filament change on my P1P without AMS, and noticed that that the “Add Pause” feature caused layer shift. I have move to using the “Add Custom G-Code” feature at the specified layer height and it’s still a little bit buggy, but gets the job done. I was wanting to put more than the two line of code to try to prime and wipe the nozzle more prior to resuming the print due to oozing, and noticed I cannot paste text resulting in typing the test G-code line by line. Also noticed that you can not fix a typo previously typed by clicking on the typo and trying to edit, you have to delete all the way back and restart from my mistake.

So my question is, can you paste text to “Add Custom G-code” or edit typos without backspacing all the way back?

I always click in the g code field and A to select all and copy to my editor to work on. Then I do the same and paste it all back at once. Working in a tiny window where I cannot even see the entire line does not work for me.

About the layer shift, yesterday’s release of the new firmware for the P1P fixes the layer shift that happened when filament ran out. I would expect/hope that it also fixes the layer shift in your case.
