Scratch 1.4 on raspberry pi has some possibilities to tweak the behavior.
This is done with a properties file ‘.scratch.ini’ which is usually located in /home/pi.
Note the dot in front of the file name, which makes it a hidden file for linux.
You need to enable the ‘hidden file’-feature in filemanager to see these files.

Change the default size of fonts used for all the texts.
Values are floating point numbers, good values are [0.7 .. 1.5]

Prevents the little sensor block dialogue to tell the using that remote sensing has been tuned on from popping up, useful for many projects
Values are [0, 1]

gpioserver = 0
Disables the gpioserver, 1 enables it, 2 makes it be on by default
Values are [0, 1, 2]
Please note that with the scratch start script, the ‘pigpiod’-code is started independent from this setting. On pi A, this takes considerable cpu power with 15-20%.

presentation= 0
Will open Scratch in presentation mode; ‘1’ will open Scratch in presentation mode
Values are [0, 1]

Some language descriptor fitting the two-letter ISO 639-1 standard
For values see https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes

Values I never tested:

home = directory for home
visibledrives = a list of drive names (Windows) or root directories (Mac) to add to the file dialogues.
share = 0 or non-0. 0 means do not allow sharing of project files
proxyserver = IP for a server
proxyport = port number for the server
renderplugin = 0 or non-0. 0 will try to force not using the PAngoCairo font renderer and likely make things ugly.
