v0.17.1

Release notes

Modification display text can be arbitrary Unicode characters

This isn't really a new feature; it was always the case. But it's worth pointing out that it is useful since Unicode has such a variety of symbols. For instance, here's unicode characters for a glowing star and medium black circle to represent a fluorophore and quencher:

Change modification connector length

You can now change the length of the modification connector. The connector is drawn like a hydrocarbon chain with a default of 4 links:

You can now edit the length:

This is especially helpful to display modifications close to each other on a helix without their text overlapping:

Autofit added to View menu

The View→Autofit submenu now has an "Autofit" option, which can center the design. Starting with a design like this:

Clicking "View→Autofit→Autofit current design" changes the zoom and translation to fit it just in the window:

Disable display of helices in main view

Go to View→Helices→Show main view helices:

Toggling it will turn off all view elements associated with helices, such as tick marks, helix circles with indices, major tick numbers, etc:

Before:

After:

Reset local settings

The File menu now has an option "Reset local settings". This will delete all settings stored in the browser, including the stored design, and reset scadnano to its original settings:

NOTE: If you need to reset local settings due to some design that is causing a bug, but the bug is preventing scadnano from loading and displaying the menu, here is how you can manually delete the local settings:

In your browser, open Developer Tools. This is Ctrl+Shift+I in Chrome and Firefox. It should also be accessible from your browser's menu, in Chrome:

In Firefox:

In Chrome, click on Application→Local Storage→https://scadnano.org

In Firefox, click on Storage→Local Storage→https://scadnano.org

Delete the key scadnano:design to remove the stored design. Delete the key scadnano:app_ui_state_storables to reset other local settings.
