From 41ababdf6c0529d4336a1daf3418ad314c373614 Mon Sep 17 00:00:00 2001 From: nicm Date: Tue, 17 Aug 2021 08:44:52 +0000 Subject: Be more sophisticated about enabling synchronized updates when there is an overlay and treat it like the active pane (use for commands which move the cursor only). When there is an overlay also use it for all panes and not just the active pane.
