Why is it called ObAddon?

ObAddon is in fact a play on Abaddon, ObAddon specifically meaning Oblige Addon as it uses Oblige's Addon system.

What do all these "As Original", "Jumbled Up", etc. theme options do?

Depending on the option you are looking at, especially with regards to theme, size, monster strength, and the Epic Textures Environment Themes option, all these behave quite differently depending on the option itself.

As Original - attempts copy the behavior of the original games. For example, in Ultimate Doom's themes, the first episode will be Tech, Deimos, Hell, and then Thy Flesh respectively.

Episodic - each episode in the WAD has a single strict theme. For example, in Doom 2, the first episode might be Hell instead of Tech, the second episode may be Tech instead of Urban, and so on.

A Bit Mixed - all options are gathered into chunks of consecutive sequences that are anywhere between 2 to 6 levels long. For example, in Ultimate Doom, the first 2-6 levels may be Deimos, the second 2-6 may be The Flesh, until the end of the campaign length is reached.

Jumbled Up or Random - all possible options are completely jumbled up and random.

[theme]-ish - this option is predominant, but has 'mix-ins' from other options. For example, Urban-ish means all maps are Urban by default, but some are elected to by any other theme. In Doom 2, you will get a WAD that is mostly Urban maps, but has infrequent mix-ins of Hell and Tech every now and then. Original-ish in Doom 2 means a WAD that follows Tech->Urban->Hell progression between episodes but then contains mix-ins from other themes i.e. a few maps in the first episode might be infrequently Urban or Hell instead of Tech.

Psychedelic - this option means blazing it.
