#7531 – Arrow icon appears in Sequence mode, violating requirement for Snake and Flex modes only
#7538 – Unable to add ambiguous monomers via arrow button - no preview and errors in console
#7539 – No tooltip shown and invalid attachment allowed when adding a monomer without R1 to selected monomer with free R2
#7548 – Tooltip not shown and addition allowed when multiple monomers with free R2 are selected
#7551 – Monomer drag-n-drop from Library to the canvas doesn’t work for peptides it they were clicked on Sequence canvas
#7562 – Tooltip overlaps monomers when hovering over arrow button on monomer card
#7575 – Monomer creation wizard opens despite selection being connected via non simple bond
#7576 – Create monomer wizard is available for structures containing S-groups, R-groups, or extended table atoms
#7577 – “Create a monomer” button becomes active for disconnected structures
#7563 – Selection after chain/monomer addition (autochain improvement)
#7580 – Zoom actions in Monomer Wizard throw errors in the console
#7601 – Wizard allows editing atoms and bonds via right-click menu without showing an error
#7604 – Name, Symbol, Natural analogue input fields are not highlighted when left empty and Submit is clicked in Monomer Wizard
#7606 – Pasting text into Symbol or Name fields in Monomer Wizard triggers unrelated “Convert error”
#7607 – Missing S-group name in KET after saving a monomer via the wizard
#7609 – Symbol uniqueness validation is missing in Monomer Wizard (no error, no highlight)
#7612 – Natural analogue is not cleared when monomer type changes
#7614 – After creating a monomer via wizard, switching to macro mode shows two separate entities instead of one
#7615 – Phantom structure remains on canvas after closing wizard and is visible in exported files
#7620 – Creating a monomer from a partial benzene selection causes console errors and no hover highlight on created region
#7624 – Created Sugars and Phosphates via wizard are not added to Macro library
#7625 – No validation against existing monomers - newly created monomer with duplicate name overwrites the existing one in the library
#7627 – Selection tools stop working after creating first monomer via wizard when many structures are on canvas
#7629 – API does not implement library change subscription
#7684 – Only selected atoms connected with bonds should be taken into account on monomer creation
#7714 – System shouldn’t allow to create monomer for selected structure that have any non-simple single bonds to non-selected parts of the structure
#7692 – System shouldn’t allow to create monomer for molecules with R-Groups attachment points
#7691 – System shouldn’t allow to create monomer for molecules with R-Groups
#7725 – Hand tool and Area Selection Tool buttons close Monomer creation wizard if pressed

Additional notes:¶

Ketcher 3.7.0 has been built and tested with Indigo version 1.35 (standalone and remote).
