From 619309ad9bf8a9882d9f13cd950eaf0eaebd73f8 Mon Sep 17 00:00:00 2001 From: John Hernandez <129467592+H3rnand3zzz@users.noreply.github.com> Date: Wed, 8 Nov 2023 09:40:14 +0100 Subject: [PATCH] Fix pagination in statusbar This commit changes the current behaviour which displays always the first tabs until `maxtabs` to display N tabs around the currently selected tab. So if we are having a maxtab of 1 and the actively selected window is 2, then 2 is displayed only. So far we have only displayed `>` to indicate that there are more windows. Since this PR shifts the range of tabs that are displayed we also add `<` indicator now to indicate windows to the left of the currently displayed.
