#463 Block name is still reserved after deletion

[LordOfBikes]

Create a block, e.g. test1
Then delete the block, the block list is empty
Create a new block test1 again, LC says that a block with name test1 already exists

this behavior is by design. in order to enable "undo" for block deletion, a deleted block is not removed from storage, only labelled as "deleted", therefore, creating a new block with the same name is not possible.

there's no easy solution here. We can delete this block permenantly, whenever user requests a new block with the same name, but it's not perfect either.

another solution:

if user requests a new block name which is taken by a deleted block, we can silently rename the deleted block.

[John Coppens]

Another solution: If the user tries to add a block with the same name as a block marked 'deleted' give a warning (effectively the same dialog box which exists), and options:

• Remove the deleted block and accept save
• Rename the new block
• Cancel the operation

Or, maybe even better (it doesn't leave the user asking why the save doesn't work):

Leave the 'marked for deletion' block in the table, with a flag 'deleted' (maybe 'grayed out'. Another delete '-' of the same line effectively deletes it.

I'll close this because of a new duplicate on github.
