This Anki add-on merges three add-ons:

• Multi-column note editor by HSSM. This add-on does not seems to be maintained anymore.
• Frozen fields by Tiago Barroso and Aristotelis P.
• Uses tex as image in editor/reviewer by myself. This add-on shows the result of tex in editor/browser.

Those add-ons seems to be incompatible, and creating yet another add-on seems to be the easiest way to have all of their features.

Use multiple columns in the note editor. You can easily change the number of columns shown using the Columns field added by the add-on, and you can have a different number of columns for different note types and window types (browser, note adder, etc).

If you have any fields that take up a lot of space, you can configure them to take up an entire row.

Note that the configuration is saved in the collection. Thus, the configuration should be shared from a computer to another one.

Anki supports '''sticky fields'''. A sticky field is a field whose value is not deleted when you switch to a different note. This can be very useful if you are making many notes in which a field either has the '''same value''' or changes very little.

Unfortunately, marking a field as sticky is quite complex and breaks your workflow. Frozen Fields allows you to conveniently mark a field as sticky (freeze) or not sticky (unfreeze) '''right from the note editor'''. It's much more convenient than the default way.

To freeze/unfreeze a field, just '''click the adjacent snowflake''' or use the corresponding '''hotkey''' (F9 by default). A blue snowflake means that the field is frozen and a grey snowflake means that the field is unfrozen.

Editor and browser won't show LaTeX's code, but the actual image, until you click on the field containing the LaTeX. This means you can actually see the result of the compilation quickly, by looking at the card you just created in the browser.

If you install this add-on, uninstall the add-ons listed above. The result otherwise could be unpredictable.

More beautiful buttons. Todos of the other add-ons.
