Attribute Changer

What's new in this version:

Enhancements:
- Enhanced Sequence view so that when two panels of sequence are visible in a split window, the minimap at the top shows the visible regions from both panels
- Enhanced cloning dialogs to fit on smaller displays
- Support polyA_site point features
- Made various textual enhancements

Fixes:
- Enhanced the GFF3 importer to handle files that mark a single sequence with multiple references
- Fixed an issue that prevented opening of some Vector NTI® .apr alignment files
- Corrected a regression that prevented files in a collection's "Working Set" from being listed in source menus in action dialogs
- Improved stability when importing protein features from another SnapGene file
- Corrected an issue that could result in poor alignments
- Corrected a regression that prevented restriction sites blocked by methylation from being shown in gray in Enzymes View using Numbers mode
- Corrected a regression that prevented sorting of restriction sites in Enzymes view by location of the first site or by distance from the selection
- Ensured proper import of SnapGene online sequence files that contain "&" in their names, such as the COVID-19 genome file
- Corrected a regression that could prevent enzymes in aligned sequences from reflecting the chosen option for displaying enzymes
- Ensured that Enzymes view does not scroll when toggling enzyme visibility
- Corrected an issue that made it difficult to trim aligned sequences by dragging a trimming handle when using double-stranded DNA format
- Improved the export to GenBank and other text formats of features that contain "&" and other symbols in qualifiers
- Improved the appearance of a selection in an aligned sequence when manual trimming partially occludes the selection
- Corrected a regression that prevented invoking the Destroy Restriction Site or Remove Restriction Fragment dialogs by pressing Delete or Backspace in Enzymes view
- Ensured that toggling enzyme visibility no longer marks a file as unsaved
- Fixed an issue that could prevent dashes within gaps from being shown when viewing an alignment to a reference DNA sequence
- Prevented aligned bases from being shown in red at the endpoints of an alignment
- Fixed an issue that could cause "Redo Alignment" to fail for some files
- Ensured that the Edit Feature dialog correctly indicates that segment ranges can overlap if features with overlapping segments were imported from GenBank or other file formats
- Improved the default ratio between the two panel heights when generating a split window
- Prevented unnecessary vertical space from being allocated when laying out aligned sequences in double-stranded DNA format when enzymes are visible
- Improved the file information shown for registered file types in the Windows Explorer and the macOS Finder
- Improved the display of aligned regions in Map view
