From 8cdee7072fe1bb3f8d663b928bec104cdd76d904 Mon Sep 17 00:00:00 2001 From: digital-garbage <133010426+digital-garbage@users.noreply.github.com> Date: Tue, 25 Aug 2026 14:32:11 +0300 Subject: [PATCH] feat(editor): Settings > Appearance gets "Show timeline on hover" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Off by default. On, the timeline sits as a strip — its header, so the title, transport and Composer stay reachable — and opens to full height while the pointer is on it or something inside it has focus. It also opens for the whole of a DRAG. During one the pointer is in drag mode and a strip that stays shut is a drop target you cannot hit, so dragenter holds it open and drop/dragend closes it. The tracker counts depth rather than holding a boolean: dragleave for the element being left fires AFTER dragenter for the one being entered, so a flag closes the strip mid-drag as the pointer crosses from one clip to the next. The strip height is MEASURED from the header rather than fixed: .zone-head wraps when the zone is narrow (34px min-height, 138px on a normal window), so any constant clips the very controls the strip exists to keep visible. It is re-measured on resize. flex: 0 0 auto matters — .zone is a shrinkable column child, and a height with min-height: 0 let the workspace squeeze the strip to 1px. The body collapses rather than being display:none so the lanes are not torn down and rebuilt on every open. A browser preference like the colour scheme, not a project one, and registered in the same Settings section for that reason. Also in this commit: - vf: train wherever there is a GPU, not only when the sample sits on one. The x0 value function's snapshot loads with map_location="cpu", so keying on the sample left it training on the CPU — the run that named it measured "x0 vf: train 10.1s" against 46ms for the same net locally. - The stage line counted nested sub-stages twice and reported 153% of a run.
