v0.1.0 - 2021/10/11

Added

• The grid can be filtered using pandas DataFrame's query and loc logic (mostly
  useful to combine with ipywidgets) with MolGrid.filter_by_index and MolGrid.filter.
• Selections can now be modified (select and unselect all, or invert) and exported (to
  clipboard or a SMILES file) even without a notebook kernel. Fixes: Issue #16.
• The grid can be sorted according to the selection status and to values in the tooltips.
• Added tracking the selection in multiple grids at the same time (i.e. it's not a
  global object that get's overwritten anymore).
• Added support for executing custom JavaScript code or Python function when clicking on
  a molecule's image through the callback argument.
• Added the mols2grid.make_popup_callback helper function to create a popup-like window
  as a JavaScript callback.
• Added styling for the whole cell through style={"__all__": userfunction}.
• Added mols2grid.get_selection() allowing users to specify which grid selection should
  be returned. Without argument, the most recently updated grid is returned.
• Added mols2grid.list_grids() to return a list of grid names available.
• Added the mols2grid.sdf_to_dataframe function to easily convert an SDF file to a
  pandas DataFrame.
• Added the custom_css argument to pass custom CSS for the HTML document.
• Added the sort_by argument to change how the grid elements are ordered

Changed

• The functions in style and transform are now also applied to tooltips.
• The sizing of the iframe displaying the grid is now fully automated and more precise.
• Reorganized the code to separate the JS, CSS and HTML templates.

Fixed

• Fixed mols2grid.save that returned an error about missing the output argument.
• The tooltip is now compatible with the "focus" mode: tooltip_trigger="focus".
• Fixed rendering SVG images in tooltips.

Deprecated

• Deprecated mols2grid.selection in favor of mols2grid.get_selection().
• Deprecated mapping in favor of rename in the MolGrid class and mols2grid.display.
