  1. The new interface design will bring a new writing experience;

  2. Set your favorite code highlighting style in the authoring center, and Markdown will display the selected highlighting style in the code snippet;

  3. Added image drag and drop function, you can directly drag and drop local images to the editing area for direct display;

  4. Brand new KaTeX math formula syntax;

  5. Added the mermaid syntax 1 function that supports Gantt charts ;

  6. Added the function of editing Markdown articles on multiple screens;

  7. Added functions such as focus writing mode, preview mode, concise writing mode, and left and right area synchronization wheel settings . The function button is located in the middle of the editing area and the preview area;

Reasonable creation of the title is helpful for the generation of the catalog

Enter 1 time directly #and press spaceit, and a level 1 title will be generated.
After entering 2 times 
#and pressing spaceit, a 2-level title will be generated.
By analogy, we support 6 levels of headings. Helps to 
TOCgenerate a perfect table of contents after using syntax.

    KaTeX math formula

    You can render LaTeX math expressions using KaTeX :

    Gamma formula displayΓ ( n ) = ( n − 1 ) ! ∀ n ∈ N \Gamma(n) = (n-1)!\quad\forall n\in\mathbb NΓ )=n!∀ nNis through the Euler integration

    Γ ( z ) = ∫ 0 ∞ t z − 1 e − t d t . \Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.Γ )=0t− 1e− tt.

    You can find more information about LaTeX mathematical expressions here .
