Yes.

This sounds like it would be modelled in-game as a successful independence war, or maybe as a long-running claimant war. It doesn't sound like a stable situation where the north permanently and irrevocably separates from the south.

One question, can all titles be created in all eras?

I have no justification for separating ireland in two.

but as an option for the court, for example the daughter of the Duke of Ulster marries the king of Ireland but in a moment of tension both factions divide or something like that.

@zorro(maxasmata) (1/2)

You should be able to create the kingdom of Mallorca as the Byz emperor (unless you hold lots of other territory in the same de jure kingdom).

For the other two, my original intention was that you would only break these duchies/kingdoms out if you were a foreign conqueror, because you don't want to be subject to the existing de jure setup... but, sometimes, I desperately want to do it anyway.

My current thinking is that a human player who owns every county in the de jure kingdom should be permitted to shatter it (eg. Byz who owns all of Anatolia can pop out Cyprus).

I just uploaded a new version which allows this, although this feature is hidden at the moment (because I'm not certain it's a good idea). To enable it, open the console and type "set_flag expd_kf_human_shattering". (This should make the decisions show up with an extra requirement "is a human player with shattering turned on".)

Re Duchy/Kingdom of Ulster: This is technically possible, but I can't think of any reasonable in-game justification (ie. flavour text for the decision). (Because the reason N Ireland is separate from Ireland nowadays is because of "culture conversion" that happened long after the CK2 period.)

If you can provide a convincing justification, which is good enough that it won't cause outrage due to current political issues, then sure, I'll add it.

Otherwise, I think you'll find it's easy to change this mod to add your own flavour.

I have a problem with this mod, I am the emperor of the Byzantine Empire and when I have Crete, Cyprus or Mallorca.

I can't get the decision to change to form these kingdoms, duchies and I have to change characters to form this.

Wouldn't it be better to have the decision on the screen when I have the county of this province, there is a county I think below Sicily, it doesn't let me transform it into a duchy, I have no idea,

but I was also wondering if you could make the Duchy of Ulster the sixth kingdom (Northern Ireland) of the British Empire. (Although I doubt you'll do that)

You're very welcome, hope you enjoy it!

And, of course, for all your efforts

that is extremely unfortunate, but if offline update downloads will do, then they'll have to suffice.

Thank you for answering, by the by!

@cpimentel Also, apparently, even after creating a very basic logo, it's impossible for me to create a collection at the moment (via Steam client, Firefox or Chrome)?!?! One problem at a time lol...

@cpimentel Nowadays, you HAVE to specify a picture to create a collection, and I've been too lazy to do so. However, you can find all of my workshop mods by clicking on the "jonjowett's workshop" link at the top of the page.

Unfortunately, I also currently have a major problem with the Workshop and am unable to update about half of my mods, including this one. (My attempted update in mid-Jan silently failed, so many of the listed features aren't actually available in the workshop version.) I have opened a ticket with Steam support, but for now the best bet is to manually install download the zip version from Gitlab: https://github.com/jonjowett/ck2_mods/blob/master/expanded_decisions_kingdom_formation/packaged_mod/expanded_decisions_kingdom_formation.zip

do you have a workshop collection? these ideas are too good to simply be lost to the ether out here
