Bordered Glass

Windows can look somewhat odd without frames, I think something so minor could add a lot of depth and detail to building, without breaking the simplicity or spirit of Minecraft. I imagine it would either be a crafted block, or possibly a modification that could be done after the glass is placed (similar to stripping wood). It would simply be a border on the glass texture, any wood, any stone, quartz, and iron/gold/copper. If you wanted to go a step further, you could make it so there isn’t a border on sides adjacent to other glass blocks.
