As is possible with other types of links, and when we put parentheses in a note. Link to open the window of Strong's Concordance with the code between parentheses. For example (H1234) or (01234), (G1234) or (1234) ? At least like that: (<a href="01234" class="strongs">H1234<a/>)
You will be able to link to the Strong's Concordance in the next update. The links will be auto-generated based on any text in the format of H+number or G+number. The references do not need to be wrapped in brackets. The links are supported both from the Notes popup window, and from inside the Notes Side Panel. Please see the screenshots for examples of this in action.
To clarify further - Strong's links are not supported inside round brackets. Round brackets are used for scripture links. If you do something like (H2345) it will render a broken link. You can just use H2345 inside the note, or square brackets [H2345] also works.
