From b8c5e8772e646fa21f6afdd2a875a1bd52848bd5 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 18:53:37 -0300 Subject: A column can be empty, as acme's can; new panes go where acme's makenewwindow puts them Newcol makes an empty column; closing a column's last pane leaves it empty with the keyboard on its tag; Delcol and Joincol alone take a column away; the session's last pane closing quits. The +New stand-in and replaceStillborn / stillborn_joiner are gone. Every new pane goes through exec.placeNew, which follows acme's makenewwindow (active column, empty column whole, blank space, halving the biggest) or, with Placement pardes, the old rules. ColumnTags is gone: column tags are always shown. A grip drag shows acme's box cursor.
