Well, the Brunei part of Borneo seems without suggestions. The current province names are anachronistic, so Kuching should be Sarawak, Jesselton should be Api, and Sibu should be Maling. Maybe a province could be added between Sibu and Brunei. Additionally, the Coast of Sarawak sea tile looks like it should border the Karimata Sea, rather than have the Straits of Johor be able to connect Selangor to Pontianak. Brunei should have some missions or historical events to represent its unique history. It also seems like it had tributary-like relations with nearby countries that would be nice to represent.
It'll be interesting to have more provinces in Borneo come alive just like Palembang, especially the one that could 'connect' Borneo to Sumatra (Pontianak?) and/or Java... Honestly, I don't see the point why Dev keep so many uncolonized territories all this time.
I think South East Asia needs more formable tags, such as one for a united Philippines and one for a country to looking reclaim the legacy of the Srivjiaya Empire.
I also personally think that it would be awesome to have a reformable Cholas tag for Cebu. Considering how many times the Cholas have fallen and then reformed, it would not be unthinkable for a strong Cebu king to reclaim the legacy of the Cholas and go full "Mare Nostrum" to control the Bay of Bengal, as the Cholas historically did at the height of their empire.
well, yes and no. It may work for the Chola, I don't know... However
- There should be no concept of united Philippine at the time, according a Filipinos in a thread some times ago (I think the thread was about Magellan the explorer)
- As far as I know, at least in, Java they don't really put importance to a kingdom's name. Like... Airlangga named his kingdom Kahuripan instead of 'reforming' Medang Mataram after he toppled Lwaram, Jayakatwang named his kingdom Kadiri instead of 'reforming' Panjalu after he toppled Singhasari, and Kertarajasa named his kingdom Majapahit instead of 'reforming' Singhasari after he toppled Kadiri.
Interesting idea, nevertheless...
I happened to become interested in the area after looking at the Indonesia thread. My thoughts on Mataram are mainly to find a way to have more historical outcomes with Java, and Mataram seems to be more significant than Majapahit during EU4's time frame. Additionally, one of those surviving sultanates, under a branch of the Mataram Sultanate royalty, are still governing Mataram, which is now the Yogyacarta Special Region .
We need to weaken Majapahit considerably if we want a more historical outcome. Majapahit is currently too strong for a crumbling empire, there's no way they will fade naturally unless Sunda defeat them somehow, but it won't result in any historical outcome in anyway.
Here are my suggestions:
1. Put a truce between Majapahit and Sunda at the start of the game, for the reason in my earlier post and for limiting Majapahit movement at the start of the game.
2. Less initial fleet for Majapahit. They shouldn't be too dominant in the sea after the civil war Paregreg. At least, less cogs, it should hinder their expansion outside of Java a little bit.
3. This is important:
apply some sort-life modifier for Majapahit rulers, maybe for the first 25 years or so. It could destabilize them quite a lot just like in history.
Historically, Suhita who was reigning in 1444 only lived until 1447, died in her 40s. Her brother Kertawijaya succeeded her and ruled until 1451, then he was succeeded by Rajasawardhana whose reign was even shorter, until 1453. After that, a 3 years period without a king before Girishawardhana took the throne in 1566 and ruled for 10 years, then succeeded by Singhawikramawardhana and thus began another civil war which ended up in king city Trowulan fell in 1478 and Demak gained independence. -- these early deaths were probably because Majapahit royal family for generations had always married to close relatives
4. Islam need to enter Java early in the game. The mechanic introduced in CoC was nice, but they need to be actively triggered by an islamic nation. And we know there's no islamic nation in Moluccas trade node in 1444, let alone one who has more than 50% trade power. Demak starting as Sunni province should be nice, I think...

Also, while looking for it, I found a historical inaccurate about Sunda. In game in 1444, Sunda was ruled by Mangkubumi Suradipati, a 70-something ruler without heir, who govern from Pakuan.
The capital of Sunda at this time should be in Kawali.
And the king should be Niskala Wastu Kancana.
Mangkubumi Suradipati was another name for King / Regent Bunisora, a brother to King Lingga Buana who died in the Battle of Bubat in 1357 together with his daughter and two sons. Because Lingga Buana's youngest son was only 9 years old, Bunisora ruled in his place until he was 23 years old and considered ready in 1371. Niskala Wastu Kancana ruled from 1371 to 1475 (104 years) and not heir-less. His son was called Dewa Niskala
