If you create a framed drawer and set the face to a transparent block such as plain glass with an opaque block as the container texture, you get a visual discrepancy depending on which direction you look from.

• looking from the front, you can see all the way through and behind the drawer
• looking from the back, you see the container texture with no transparency

Based on how the drawer looks to me like it's constructed, I feel like looking from the front should show the container texture at the back, so thought I'd report it here in case you feel like it's worth addressing. Obviously just a visual oddity so not the end of the world if you decide not to change this. Thanks for an awesome mod!
