ZCode Agent（自研）

使用场景 · Use case

First, credit where it's due: the mobile app is genuinely strong and useful — the core (agent runs, sessions, remote control) works, and I use it daily. But it is not yet convenient: on mobile every check-in is short (one hand, on the go, seconds of attention), so small ergonomic frictions cost far more than the same friction would on desktop.

The community backlog shows small convenience items accumulating without a dedicated track, for example:

• #454 — quota/context button unclickable on touch devices (CSS hover lock)
• #228 — large sessions fail to open on phones (relay frame limit)
• #255 — session titles truncated despite free space
• #254 — wide tables/code blocks drag the whole page sideways (missing overscroll containment)
• #92 — H5 remote page requires manual zoom (fixed-width layout)
• #305 — no voice input / dictation on mobile

None of these are hard engineering problems individually — but together they define how "convenient" the app feels day to day.

建议方案 · Proposal

1. A fast-follow UX-polish track for mobile. Batch several small ergonomic fixes (touch targets, layout overflow, truncation, zoom) into frequent minor releases, instead of bundling them with large feature releases. Most of the items above look like days, not months, of work.
2. Treat "open session → catch up → act" as the primary mobile flow to optimize: reliable opening of large sessions (#228), always land on the newest message with a "jump to latest" affordance, quick session switching one-handed.
3. Voice input (#305) as a first-class convenience feature — on mobile, dictation is often faster than typing.

预期价值 · Expected value

Mobile is where quick check-ins happen; per-check-in friction multiplies across many short sessions every day. Faster small-fix releases compound into a noticeably more convenient app without waiting for major versions — and they directly improve perceived quality of an already strong product.

补充材料 · Additional context

• Related: #556 (chat UX improvements — sticky latest prompt and inline media previews apply to mobile too), #469 (timeline/navbar UX).
• Happy to help with repro steps, device details, or beta testing for any of the linked items.

This is an umbrella proposal rather than a single implementation target; start by reviewing the referenced issues #454, #228, #255, #254, #92, and #305, plus related #556 and #469. Choose one concrete mobile UX fix with reproducible steps, then verify the selected behavior on an iOS device or the stated mobile flow.
