You need to change to a more macro-friendly selection method.

Personally, I love to use selection by layer (SELBYL) since that means you don't have to go for specific coordinates in the macro. Just make sure the hotspot is on the appropriate layer, and don't put anything else there.

Remember to reset the selection method when done. Usually best to save it with SELSAVE, and restore it a the end of the macro with SELREST

Try now, it should be fixed, it was some missing permissions.

As for deleting thing, users can delete their own comments, but not threads. This is because a deleting a thread would also mean deleting any comments in it, which may belong to other people. This is Vanilla's own reasoning for why the system is like that, and not an option I can toggle.

I don't think that should be any issue.

When deleting an entity, it isn't removed from the drawing list untill the next save anyway, it is just marked as deleted, so even if the code running the macro needs to hold a reference to the entity (which I don't know if it does), it should still be valid.

Haven't tried this though. I recommend you give it a go in a simpler test scenario first.

No, it is not currently possible to switch them on the fly. There are to many differences between the editors in javascript that has to be loaded, different CSS files and so on. Normally, it isn't possible to switch editors at all, the options to change them via the edit profile was a plugin I wrote myself.

It isn't like the old forum where everything was basically the same editor, the switch on the bottom just told it how to interpret the codes you had in your post, it didn't really change anything on the client side.

And the format these editors use to store the information is VERY different, so I am quite confident that a draft from one of them will not work in the other.

While everything is technically possible, I am not very likely to add features that are not available as an add-on. There are a lot of various requests for all kinds of potential improvements here now, but all of those means that I basically will need to write a new plugin myself.
