draw.io
I'm making class diagram in draw.io.
I add a package and a class to the paper.
How do I add the class to the package? (just plain putting it there on the package seems silly and what if I wanted to move the whole package?)
Aditional question: is there any way to move the name of the package away from the center of the package?
Try File, Edit and replace shape=xy with shape=zx using a text editor.
The links that Google provide to publicly visible files aren't actually the raw file, they are a link to a Google page that has an indirection to that file.
In order to get the raw file the file must be placed in a publicly visible folder, being public on its own isn't enough.
Next, Google decided to remove your ability to get the raw URL of the file in the new Drive UI. You need to click on the cog top right and select "Leave the new Drive". In the old Drive UI select the file, then the "Details" panel on the right:
You'll then get the raw URL under "HOSTING":
That's the URL to paste into "Public URL of the diagram"
Obviously, Google seem to be wanting to remove public file raw URLs, we are thinking about an alternative to this when they remove the old Drive UI completely.

I figured out that you can do this by doing voodoo magic. Select the package and then click on the "Text" tab, next make sure the position is to the left and then select the Arrow with the line over (it's highlighted in the image), next set the top spacing (I made mine -5pt). This is the best quick way of doing this without having to do so much work. Copy and paste also works for multiple packages. You can also adjust the size of the space by selecting the orange circle (in the image below). I hope this helps someone.
