Should have the ability to use a lossless output like PNG. Scientists will almost certainly want TIFF output too. One question is how to preserve Exif data with these other formats (ought to be possible with TIFF given that's where Exif originated - no idea about PNG and whether PIL/Pillow supports writing Exif at all, let alone to non-JPEG formats).

Permit user to configure DHCP/static addressing, DNS servers, hostname (does this affect DHCP client ID?), and client IP lock (still need to add the latter).

If possible, attempt to interface to the camera directly with MMAL. If this is successful, attempt to incorporate image overlays (OpenGL/ES?)

Now we can configure thumbnail settings in picamera, it might be worth seeing if we can extract the embedded thumbnail from JPEGs and use it instead of a separate thumbs directory?

Need a wrapper script which will start picroscopy on boot and, depending on exit code, shutdown or reboot the RPi, or possibly upgrade picroscopy (if possible?)

Assuming new installation will be using DHCP and that the RPi will have no (proper) DNS name. Display IP address prominently on startup (image? ASCII art?).

Side issue: what if RPi is using wlan0 instead of eth0? Should we support this?

Users should have the ability to specify the level of compression of the JPEGs. There should probably be some warning for silly settings like <75 or >95.

Check out how to draw scale bars on generated images then provide the following settings:

• Scale bar enabled/disabled
• Scale bar position (top-left, bottom-right, etc.)
• Selected lens

In the configuration file, use a separate section to dictate the available lenses and the scale of their scale bars, when active
