## Version history (last 3 releases)

### 1.2.0 — 2026-10-30

• Upload a photo of your signature is now supported
• Various alignment options via the right click menu on markups, measurements and stamps
• Vertical alignment of text within a callout or textbox
• Stamps are quicker to place: set rotation, flip, tint and opacity before you place, and keep dropping copies until you press Esc or switch tools. 
• Undo and delete are more dependable: deleting several items is one undo step, and deleted markups no longer come back after a dropped connection.
• One document menu everywhere, with a new Permissions window that shows who has access. 
• Sharing is simpler: email invites give access straight away, and only editors can create share links.
• Properties panel: a tidier, consistent layout, and set width and height in feet, inches, millimetres and more on a scaled page.
• Lists: Shift-click to select a range and ⌘-click to add items, plus a Fill colour column and grouping in the sheet.
• Fixes and polish: export file names, a refresh button for your document list, covers fade in smoothly, and a cleaner launch screen on iPhone.

### 1.1.0 — 2026-10-26

• Custom stamps: import your own stamps from SVG, PDF or .btx files, organize them into groups, and place them at true size on scaled pages.
• Legend: drag out a legend that sums up your measurements and markups, with styles, totals and reorderable rows. It's included in exports too.
• Custom fonts: use Google Fonts or upload your own for text markups and labels.
• Area measurements can show their perimeter as a second label, and you can type any custom page scale.
• Document tools (Organize, Extract, Merge, Compress, Share and Export) now work on documents in your Local Drive and in Files or Finder.
• Share links have been fixed so they open the document right in the app if it's installed.
• Fixes and polish: Convert works again on Mac, curved cutouts fill correctly, a better selection bar on iPhone, and you can place images up to 25 MB plus over 50+ bug fixes.
