Added

• The ability to create new drawings from CT "Connectivity Table" files. CT files are produced by structure prediction programs such as Mfold and RNAfold.
• Checkboxes that control whether or not a line is dashed now also have text boxes that appear next to them in which the pattern of dashes can be specified. The pattern of dashes corresponds to the stroke-dasharray SVG attribute (see MDN page for more info).
• Elements such as squares, circles, triangles and text can now be strung on the lines of primary, secondary and tertiary bonds. This allows for things such as non-canonical base-pairs to be depicted using the Leontis-Westhof notation and for GU wobble base-pairs to be depicted as dots, for instance. See section on strung elements for further explanation.

Changed

• Removed fields to make the lines of primary and secondary bonds appear as dots and squares. Circles and squares may now be directly strung on primary and secondary bonds instead (and the lines of primary and secondary bonds made to be invisible).
• Changed the list of preset colors that appears at the bottom of color pickers.

Fixed

• Fixed an issue where the file explorer would sometimes not open after pressing the upload button in the form to open a saved drawing.
• Increased the precision of base padding attributes for bonds and numberings to two decimal places. (Base paddings will now be more accurately maintained when opening and saving drawings and on undo/redo.)
