Here is the wishlist I'd like to have for the next major version:

• Don't use Grid for table header
• Replace react-virtualized with react-window replace react-virtualized with react-window #12
• remove deprecated lifecycles migrate to new lifecycles #10
• Dynamic row heights feat: add support for dynamic row height #170
• Make virtualization configurable
• A11y
• UT
• plugin support
• rewrite with TypeScript
• support custom children key

Breaking changes:

• use rollup to bundle package
• omit placeholders in rowRenderer
• rename tagName to as or elementType
• rename scrollToPosition to scrollTo
• rename headerRenderer to headerRowRenderer
• rename headerRenderer for Column to headerCellRenderer
• move AutoResizer to a separate package

Nice to have:

• better size calculation to support cell with borders Resizer line mis-placed when using padding/margin/borders on the cells #149
