Thanks for reviving this! It would even more excellent if the functionality of the old Quote Collapse could be incorporated.

Edit: Thanks. If I may suggest a fairly simple way: wrap the quoted block in a <details><summary/>[quoted block]</details> structure. The summary might contain the first line of the block text.

From up version 3.0a7 you can collapse the quotes. This has to be enabled in addons options.
