Same with caddy, except that time it was my money.
Some times I wonder if I should avoid giving money to open source projects because it seems to trigger the idea that one can make a whole lot of more money by selling out.
It's also not very performant. Rendering often forces multiple style/layout recalculations, which is nearly always solvable by having your rendering code better organized. Version 8, when they rewrote cell meta, caused certain cell meta APIs we were calling to take _seconds_ on large tables. Version 9 did not document that the "beforeManualColumnMove" changed the meaning of the indices from "before columns" to "after columns". Undo/redo is implemented incorrectly too, so we had to write that ourselves. These caused real problems that affected our users.
As soon as we get the capacity to switch to something like Datagridxl2 we will.
