v0.2.0

Feature release centered on Sanger chromatogram (AB1) display, a redesigned primer-alignment view, and much richer read-alignment rendering.

New Features

• AB1 chromatogram display — opening a .ab1 file now shows the Sanger trace alongside the sequence, and alignment reads with trace data can expand a chromatogram band under their lane; bands collapse behind a per-track label toggle
• Reads align across large internal template deletions — a read spanning a big deletion in the template is now split-aligned onto both flanks instead of failing to place
• Alignment gaps and insertions render as placeholders — large indels are drawn as compact dot-pair markers (with hover highlighting per insertion, group hover, and a right-margin label) instead of stretching the layout; an insertion popover lists the inserted bases
• Primer alignment details redesigned — the primer-vs-template view now shows flanking context, position markers, base-level highlighting, and unaligned 5' tail overhangs
• Linearize / Circularize toggle — DNA projects can switch topology from the Edit menu
• Enzyme context menu — right-click an enzyme site for related-enzyme navigation; enzyme lists auto-scroll while dragging
• Sidebar project tabs — long names scroll on hover, and tabs can be reordered with a long-press drag
• Feature deletion shortcut — clicking a feature then pressing Backspace once deletes the feature, twice deletes the underlying sequence

Improvements

• Tm now matches SnapGene — melting temperatures use the SantaLucia & Hicks (2004) initiation parameters
• Hidden alignment tracks persist per file — tracks you hide stay hidden across reloads
• Nav bar interactions — left-click runs the default action, right-click opens the menu
• Overlapping feature labels — hovering a feature raises its label above the crowd
• Map watermark simplified — feature labels are hidden in the watermark, keeping just the plasmid name and size
• Dialogs — Esc closes the search bar and layered dialogs; the feature dialog requires resolving a pending location edit before closing; the primer dialog defaults to a wider minimum width
• Save dialog prefills the name entered for unsaved projects, and duplicate feature names are allowed when creating features
• Homebrew tap updates automatically on each release

Bug Fixes

• Features with identical ranges now all render instead of being deduped
• Clicking blank canvas areas clears the selection
• Primer alignment windows extend past reverse-primer footprints and wrap correctly at the circular origin
• Newlines are stripped from primer sequences parsed from wrapped GenBank notes
