-Added: numbered drag handles next to each layer in the mixer. Long-press a number box and drag to reorder layers in the stack (replaces the previous up/down arrows). Volume % input beside the slider remains for precise volume entry. -Changed: raised the audio engine max layer count from 12 to 20 so it matches the mixer's 20-layer limit (adding a 13th+ layer previously failed in the audio manager even though the UI allowed it). -Added: soundscape names in Discover that don't fit on one line now slide (marquee) to reveal the full title, looping with a pause at the start and end; short titles that already fit are unaffected. -Fixed: cutting a layer sometimes trimmed a slightly different region than what was visually selected. A fast drag-then-cut could read a stale guide position instead of the one shown on screen; the cut now always uses the exact on-screen selection. -Fixed: layers from "My Sounds" (AI-generated) showing as the generic label "AI Sound" under a soundscape's name in the Library. They now show the sound's actual (possibly renamed) name. -Fixed: fade-in/fade-out glitching after shortening or lengthening a layer. Fade regions were left anchored to the layer's old (pre-trim) duration and could point past the new shorter length; they are now re-clamped to the layer's new duration whenever it changes. -Fixed/Stabilized: the UNDO button. It previously stored only a single last-action slot, which its own restore logic could overwrite mid-undo, so a second edit silently erased the first one's undo data and a failed restore could corrupt the next undo. Replaced with a proper 20-step undo history. UNDO now reliably covers: adding/removing a layer, trimming/cutting a layer and its fades, and layer position/volume changes. -Fixed: two layers using the same sound stacked on the same timeline position and rendered visually identical (both defaulted to the same color slot), making them look merged into one layer. Each new layer now gets a distinct timeline color so duplicate-sound layers stay visually distinguishable. -Fixed: detailed mixer's Simple/Detailed view toggle sometimes stopped responding ("tabs" not registering). The switch-view transition cleared its "switching" lock through a chain of animation-frame callbacks with no fallback; if that chain was ever interrupted (e.g. app backgrounded mid-switch), the toggle stayed disabled permanently. Added a safety timeout so the toggle always re-enables.

-Fixed: other sounds glitching when a layer starts via the playhead (especially with more layers active). Cause was every currently-audible layer force-reseeking its native player in the same instant on each loop/scrub; re-seeks are now spread a few ms apart so they don't contend on the shared audio engine. -Fixed: saved soundscape layer names not matching the real sound name. AI-generated ("My Sounds") layers were always relabeled "AI Sound" on reload instead of showing the sound's current (possibly renamed) name; now resolved live from the sound's current name every time a soundscape loads. -Fixed: deleting a sound from the library no longer leaves it playing/orphaned in the mixer. If the deleted sound is currently loaded as a live mixer layer, that layer is now removed automatically. -Fixed: volume slider percentage label freezing while dragging in the detailed mixer. It now updates live as you drag, matching the audio (which was already live). -Fixed: loop tiles not visually covering the whole timeline for continuous loops on extended (longer) timelines. The timeline renderer had a fixed cap on how many loop tiles it would draw; raised so long timelines with short continuous loops render correctly end to end. (Actual audio playback was never affected — this was a visual-only issue.) -Fixed: sound level not scaling reasonably — 1% and 50% volume sounded almost the same. Volume now follows a perceptual curve instead of a raw linear scale, both in live playback and in exported/baked soundscapes. -Changed: increased the max loop gap for sound layers from 1 minute to 3 minutes. -Added: an Undo button to the left of the middle transport buttons below the timeline. Undoes the last mixer edit (volume, speed, loop, offset, effects, cut, timeline length, layer add/remove, reorder). -Fixed: adding the Undo button pushed the timeline length controls out to the right. Transport buttons are now smaller and spaced tighter so the row fits without shifting.

-Shortener for Detailed Mixer's timeline added. -Overlapping bug for extended soundscapes fixed. -Adding same sounds multiple time is now allowed in soundscape generation.

-Storage usage limited for users. -Bug on mixer that causes unable to save soundscapes which uses fade-in/fade-out effects fixed.
