History trees are one of SnapGene’s most powerful features, but large history trees make sequence files unwieldy and slow the simulations. Now you can automatically limit the size of history trees, or manually trim history trees for individual files or sets of files.

Files in a collection can now be organized in nested folders. The file hierarchy is visible with an optional folder view.

For DNA files in a collection, a versatile interface allows specification of the code number format. Newly added or imported files can automatically receive sequential code numbers.

Files of interest in a collection can be assigned to a "Working Set". Those files are then easily accessed both in the collection and in cloning windows.

Files in a collection can now be sorted either by “Date Added” or “Date Created”.

The Choose Enzymes dialog offers new options for specifying the properties of the recognition sequence.

An "Order" button has been added to the top toolbar.

"Gap" features are now supported.

When saving to a collection, you can now specify which folder to save into.

Sort the files in a collection in either order according to date or code number.

Entire plasmids can now be ordered directly from VectorBuilder.
