# Stacks
yabai can stack windows in one tile, but shows only the one on top. Yabar marks every stack so you can see what is in
it and pick a window with a click.
- [Indicators](https://docs-v3-preview.elastic.dev/yabar/stacks/indicators): icons, pills or i3-style tabs, and where they go.
- [Room](https://docs-v3-preview.elastic.dev/yabar/stacks/room): how Yabar keeps them beside your windows, never over them.
- [Attention](https://docs-v3-preview.elastic.dev/yabar/stacks/attention): badges for windows that want you.
