Qu Yi submitted an update to the
spbmark
package.
Version number: 1.39 License type: cc-by-4
Summary description: Customize superscripts and subscripts
Announcement text: ----------------------------------------------------------------------
Bug fix: - Horizontal mode is entered when a superscript or subscript command is used at the beginning of a line.
Added: - Added three commands llastwd, clastwd and lastwd to save the width of the previous mark for successive negative movement of the next mark.
Enhanced： - The distance moved can be expressed mathematically, for example 'hmove=3bp*2-10pt/2'.
