Working with columns
Each account is displayed as one column (a vertical pane), side by side.
Screen layout

| Area | Role |
|---|---|
| Left sidebar | Navigation (top), account icons (middle), settings ⚙ / language 🌐 / Inbox 📥 / compose ✎ (bottom) |
| Column header | Service icon, back/forward, username, unread badge, hide/delete buttons |
| Column area | The account's SNS screen |
The active column
Sidebar navigation and the compose button act on the currently selected "active column". Its header is highlighted with an orange frame; there is always at most one. Click a column (or its header) to switch.

- Keyboard: Cmd/Ctrl + a digit (1–9, 0) switches to the corresponding column.
Navigation (sidebar, top)
Navigate the active column to Home, Search, Notifications, Messages, Bookmarks, Profile, and so on. Items a service doesn't support are disabled (greyed out) — e.g. mixi2 / Substack are mostly Home and Profile.

The compose button
✎ (Compose) at the bottom of the sidebar opens the active column's empty composer (different from "delivering" a draft — that happens from the Inbox).

Hiding and re-showing
- − (Hide) in a column header temporarily removes that column from the screen. The session (login state) is kept; click the sidebar icon to show it again.
- × (Delete) in the header deletes the account itself (its session data is removed permanently — this cannot be undone).

Reordering & scrolling
- Drag a column header to reorder columns.
- When columns don't fit the window, ◀▶ rails appear at the edges to scroll the visible range.
