v0.3.0

What's New

Interactive Controls Panel

• Sliders (0–100), checkboxes (on/off), and buttons (press counter) that write values into the engine's name system
• Formulas referencing control names (e.g. =RATE * Amount) update live as controls are adjusted
• :ctrl add slider|checkbox|button <NAME> / :ctrl remove <NAME> / :ctrl list
• F3 focuses the controls panel for keyboard interaction; Esc returns to the grid

Right Panel Layout

• Right panel now visible when either a chart is active OR controls are defined
• Vertical split adapts: chart+controls 50/50, chart-only 100%, controls-only 100%

Key Binding Changes

• r, q, c removed as nav-mode hotkeys — these characters now start cell editing
• Use :r (recalculate), :q (quit), :chart (toggle bar chart) in command mode instead

Two-Column Help Screen

• Paste Special and Command mode sections displayed side-by-side
• Colors palette split into two rows of 8 for better fit
