UPDATES & CHANGELOG
+
v1.13 ( April 2026)
  • Added a new "Maximize drawer capacity" feature in the expert settings.
  • This function allows you to utilize the dead space under drawers when using overlay fronts and thick cabinets. Inner boxes are automatically extended downwards to maximize storage space.
  • Updated and clarified tooltip texts for a better understanding of the calculator's behavior.
v1.12 ( March 2026)
  • Added the option to choose the cutting layout method: "In strips" (easier cutting on a panel saw) or "Tetris" (maximum material yield).
  • Major optimization of the sharing URL – thanks to shortened parameter names and smart rounding, the link is now approximately 50% shorter.
  • Completely reworked calculation sharing on mobile devices – now uses native phone sharing, solving the issue with long URLs being cut off in apps (e.g., Messenger).
  • Fixed an issue with URL parameters being cut off when sharing to Facebook.
v1.11 ( March 2026)
  • Added the ability to include cabinet parts directly into the cut list (choice between a full top panel or support rails).
  • New features for easily sharing a specific calculation (URL link and social media icons) have been moved to the main panel and are now unlocked for all users.
  • Optimized the graphical layout of the export and sharing buttons – cleaner display on desktops and perfect adaptation for mobile devices.
  • Added explanatory tooltips to the new cut list settings to make it easier to understand which parts are calculated.
v1.10 ( March 2026)
  • Added a new graphical cutting plan feature directly into the exported PDF.
  • Partnered with OptiCutter to provide highly efficient cutting optimization (material yield over 90%).
  • Added the option to maintain wood grain direction for drawer fronts in the cutting plan.
  • Ability to define custom board sizes (separately for fronts and drawer boxes).
  • New input for ABS edge banding thickness (the calculator automatically deducts the edge from the cutting dimensions).
  • Overall redesign and improvement of the exported PDF document for maximum clarity in the workshop.
  • Added a multiplier (repeater) function for the cutting plan – easily generate parts for multiple identical drawer sets.
v1.02 (March 2026)
  • Added support for 0 mm cabinet material thickness (outer dimensions now equal inner dimensions).
  • Fixed handling of zero thickness in JavaScript and corrected its display in the PDF export.
  • Complete fix for tooltip centering on mobile devices.
  • Improved logic for displaying right and left columns.
  • Updated and expanded tooltips for input fields.
  • Added automatic values (Inner dimensions) below the Outer cabinet width and height fields.
v1.01 (February 2026)
  • Added new modern Dark-mode design for the calculator.
  • Improved expert settings functionality for professionals.

Key Features:
  • Blum & Classic: Switch between undermount slides (Tandem/Movento) and classic ball-bearing slides.
  • Overlay & Inset fronts: Automatically recalculates all depths and clearances.
  • Individual heights & smart calculation: Need one drawer higher? Just enter its size and the rest is automatically calculated to fit the remaining space.
  • Save configuration: Easily save your project and return to it anytime later.
  • Pro Cut List (OptiCutter): Automatically generates a graphical layout for the panel saw with maximum material yield. The PDF includes exact slide placement, drilling axes, and a QR code to return to your configuration.
  • Advanced Formatting: Set custom board dimensions, automatically deduct ABS edge banding, and keep track of wood grain direction for perfectly matching drawer fronts.
  • Cabinet multiplier (repeater): Need the same cabinet with drawers multiple times? Just enter the quantity, and the cut list will generate parts for all sets at once.
  • Multi-language & Units: Works in English with the ability to switch between metric (mm) and imperial (inches/fractions).
  • And much more...
