Subject: Revert "Bugfix: set group mask 1 by default, correctly compare modifiers"
X-Git-Tag: 4.12~105
X-Git-Url: https://git.sur5r.net/?p=i3%2Fi3;a=commitdiff_plain;h=e48c4cd25700fac9bf1eb85c3ffec5f43348a90d

Revert "Bugfix: set group mask 1 by default, correctly compare modifiers"

This reverts commit 9692c1498bcde3489f80b484dbd847a75dfd0405.

That commit accidentally defaulted to group mask 1, but the default
should be to match any group mask, so that having multiple layouts
loaded at the same time works.

fixes #2062
