Insights can now filter out limited blocks from WorldEdit! You can even configure a replacement block which Insights should use instead, or you could leave the blocks unchanged - your choice! This is (for now) unfortunately only for servers running 1.13 or higher (WG7). I hope to find an alternative for WG6 in the future.
Insights can now be configured to disable asynchronousity on a block level. This could improve support for plugins which transform blocks in special things (e.g. MFHoppers @dinoboss2001)
Fixed an issue where it was not possible to leave messages blank. Insights will now respect blank messages - these won't be send to the user.
