Improved Windows
by CreepSkeet
Improved Windows changes how glass panes, iron bars and stained glass panes connect to nearby blocks, so panes meet slabs, stairs and other pane blocks without gaps.
What it does
Pane blocks normally stop short of slabs and stairs, which leaves floating gaps in glass walls and window rows. The mod lets panes connect to slabs, stairs, windows, railings and walls, so the joins line up as the builder intended. Connections form automatically when a pane is placed beside a supported block, and no setup is needed for the default behavior.
The mod targets glass panes, iron bars and stained glass panes, and it is compatible with panes added by other mods as well as the vanilla ones. Servers that run it need every player to install it too. Files are published for Forge only, for three game versions: 1.16.3, 1.16.4 and 1.16.5, with v1.0.1 for 1.16.5 as the latest file. The code is not open source, and the mod is released under All rights reserved.
Key features
Pane connections to slabs
Glass panes and iron bars join slab tops and bottoms, so partial-height walls no longer leave openings.
Pane connections to stairs
Panes attach to stair blocks, closing the gaps that appear where a glass wall meets a roof or staircase.
Windows and railings
Panes also connect to windows, railings and walls, which lets a single pane run continue cleanly across mixed blocks.
Automatic joins
Connections form on their own when a pane is placed beside a supported block, with a configuration option for changing behavior.

How it compares
Horizontal Glass Panes is an open source option for Fabric, Forge and NeoForge, released under the GNU General Public License v3.0 only and covering 1.20.1 – 26.2. Glass is a Fabric and Forge mod under All rights reserved, covering 1.16.5 – 1.20.1. Improved Windows is a Forge-only, closed mod for 1.16.3 – 1.16.5, so its range does not overlap with Horizontal Glass Panes.
