[repo:objectui] View tab bar caps visible tabs at a fixed maxVisibleTabs = 4 — 8 queues on a 1440 px page render 4 + '还有 4 个' with ~700 px of empty bar #14883

Summary

The object list page's view tab bar shows at most 4 view tabs regardless of available width. An object with 8 list views on a 1440 px viewport renders 4 tabs, then 还有 4 个 ({{count}} more), leaving roughly 700 px of the tab bar empty. The queues a role needs most (here: 待领导审批 / 已通过 / 已归档 / 流程看板) are hidden behind the overflow menu for every user, on every screen size.

Minimal reproduction

Platform 17.2.0 console, viewport 1440×900 (also 1920).

1. Define an object with a list view plus 7 listViews (short 2–5-character Chinese labels; here 全部填报单 / 填报中 / 分公司核对中 / 待人力审核 / 待领导审批 / 已通过 / 已归档 / 流程看板).
2. Open the object list page.

Measured in the page (DevTools, data-testid="view-tab-bar"):

viewport 1440 · tab-bar width 1152 px · parent width 1184 px
visible tabs: 全部填报单, 填报中, 分公司核对中, 待人力审核
overflow button: "还有 4 个"

The four visible tabs occupy ~430 px; the remaining ~720 px of the bar are blank.

Where

plugin-view chunk of the console — the tab bar component destructures its options with a fixed default:

let { showAddButton:S=!0, inlineRename:C=!0, contextMenu:w=!0, reorderable:T=!1,
      maxVisibleTabs:E=4, showIndicators:k=!0, ... } = i
...
{visibleViews:U, overflowViews:fe} = useMemo(() => {
  let e = H.slice(0, E), n = H.slice(E); ...

No ResizeObserver / width measurement participates; E is not set from view metadata anywhere I could find.

Expected

• Overflow should be width-aware: fit as many tabs as the bar can hold (measure, or CSS container query), and only then collapse the rest into {{count}} more.
• Or, at minimum, let the app author raise the cap from view metadata (e.g. a tabs.maxVisible / listViews display option), and raise the default well above 4 — most business objects have 5–8 status queues.
• Keep the current behaviour (active tab promoted out of the overflow) — that part is fine.
