- add `oneColumnModeDomSort` true|false to let you specify a custom layout (use dom order instead of x,y) for oneColumnMode `setColumn(1)` [#713](https://github.com/gridstack/gridstack.js/issues/713)
3233
- fix oneColumnMode to only restore if we auto went to it as window sizes up [#1125](https://github.com/gridstack/gridstack.js/pull/1125)
