This fish tank would look much better with connected textures.

On the left side is plain glass blocks, on the right side is PITG glass panes

Maybe an alternative:

• Allow me to specify the exact tint as a config option, so I can repurpose plain white tinted glass a clear panes
• Make a plain clear glass pane

I've started looking at connected textures, it is a bit more complicated for complex shapes. Once I get a bit more time, I can start planning the next major update.
