[ZhuchkaTriplesix]

Scope

Manual QA before tagging 0.4.11.

Core smoke

• Fresh profile: connect PG / MySQL / Redis / Mongo / SQLite
• Secrets survive restart; delete connection works
• New Connection from URL
• Help → Check for Updates sees GitHub Latest (after tag: 0.4.11)

Extensions (from 0.4.10 + deltas)

• Install local .zip/.qext
• Sandboxed driver: SDUI form → connect → tree → SQL / table
• ExtensionTableView toolbar / filter / count (enhancement(ui): upgrade ExtensionTableView with TableToolbar, custom SQL filter, and async count calculation #324)
• New RPC methods don’t break handshake (enhancement(marketplace): extend SDUI RPC protocol with getCapabilities, getServerStats, getObjectDDL, and cancelQuery #323)

Export / parity / shell (new in 0.4.11)

• Results export: CSV, JSON, Markdown, SQL dump (enhancement(ui): add universal data export (CSV, JSON, Markdown, SQL dump) to ResultsTab #326)
• MySQL + SQLite: tx controls / DDL / stats parity (enhancement(connections): align MySQL and SQLite workspaces with PostgreSQL UI standard (tx controls, DDL view, stats tab) #325)
• Empty workspace recent connections + primary CTA (epic(ui): harden desktop shell UX, accessibility, and visual consistency #339)
• Tab strip keyboard; toast; overlays via showAppDialog
• Virtual grid column resize (bug(ui): fix column width state synchronization in VirtualResultGrid #331); timeout closes connection (bug(workspace): force-close connection upon query TimeoutException to prevent protocol errors #333)

Motion regression

• Preferences Motion Full / Reduced / Off still works

Parent: epic(release) 0.4.11.
