I added further pull requests for float left, with a CSS option for float right, moving the strikethrough button to be with the bold, italics, and underline buttons, and created a basic columns button. The last may be better as its own component or pushed to the pop up menu.
I removed the pull request; it needs further modifications. I am also looking to add superscript and subscript buttons, but once you add in calendar events, slick, and tiles, there are too many buttons on the composer in mobile’s vertical composer. It shouldn’t be a problem in horizontal, but if all buttons should be accessible from either menu, then they should be moved into the pop up.
Any thoughts, @Steven, on how you want to handle this?
I will just split the main js into two files and work on some responsive CSS.
Ideally we should also add settings to disable/hide the buttons as desired.
EDIT: I’ve implemented the changes mentioned (but elements do not have an option to be hid outside of CSS) and just need to test the changes before submitting a PR.
