Performance Improvements

We shipped a big performance improvement in this release. Everything from uploading files to calculating formulas should run faster now. And undo redo history should be preserved nearly perfectly.

In addition, we made a handful of other quality of life improvements

• Fixed plain text HTML pasting into Subset
• Fixed changing decimals on number formats that use semi-colons
• Added support for IFERROR formula
• Double clicking a cell opens the formula editor in edit mode
• Cutting a cell with a formula that references other cells will translate the formula references automatically
• Undo and redo now supports cell formats and translated formulas
• Tab moves the cursor to the right
