ColumnPad v2.5.0

[Awetspoon]

What changed

• Rebuilt column sizing around saved Standard, Custom, and explicit Fit modes while keeping global snap/spacing, per-column controls, and both workspace and editor scrolling.
• Added adjustable gutters, per-column text colours, aligned ruled-paper styles, portable native-layout pictures, and clearer Actions menus.
• Replaced Markdown file/export support with concise readable JSON exports and strengthened save, session, recovery, validation, and migration behavior.
• Simplified Workflow Builder creation, linking, placement, persistence, and older-workflow migration.
• Updated the solution to .NET 10 LTS, added Windows CI, expanded regression coverage, refreshed public documentation, and prepared v2.5.0.

Why

Column width, snap, reset, and add-column behavior had become coupled, so adding columns could shrink the whole surface and reset could report success without a visible result. This update gives each behavior one clear responsibility and protects the surrounding editor, file, recovery, and workflow features with focused tests.

User impact

Users get predictable fixed-width columns and horizontal scrolling, an optional equal-width Fit mode, reliable reset/freeze controls, clearer editor appearance controls, portable saved pictures, and a simpler Workflow Builder.
