Hey, just wanted to say, thanks for this tool, it's a great utility!
A few notes on the forced Journey Mode for other worlds:
There's a couple of things that don't work as they should though, the text on item tooltips saying how many are needed to fill the Research, and the hotkey associated with the menu don't work; these haven't been solved on the FE forum's CE table, but you HAVE solved the Enemy Spawn Slider, and I'm so damn happy about that!
Also, setting the Enemy Eifficulty Slider to 1.0 (Classic) seems to set the health values for the world type as they should be (f.e. blue slimes have 411 HP on master mode), meaning you can set the enemy difficulty to half of what it should be or 3x (1785 vs 10710 for king slime), but still get the Master (or expert) stuff depending on the world you set. Nice way of making stuff harder or a bit easier without gimping your rewards.
EDIT: after testing it out with different characters, I've come to the conclusion the hotkey and tooltips are tied to the character, just like the research itself, so there should be a flag somewhere that enables them on the character file, but that goes into inventory editing... ah well.
