[DASHBOARD] Allow moving a block from one column to another

Hello @guim31,
Indeed, the feature request already exists:

Following your remark and being on vacation, I took the time this morning to add tags to the feature requests to improve searches. I hope that will help going forward.

Also, @pierre-gilles will confirm if I’m wrong, but it seems to me that he is using another request to improve this as well — just not sure that it includes the « between columns »:

So @Lokkye, @gaelbillon, @Kevin, @Einstein8854, @Jluc, @qleg and @guim31, I suggest you cast your votes again on the other thread and that we close this one, hoping you’ll get your votes back soon after @pierre-gilles’s PR ^^.
