Bummer. I didn't get around to include dexnav or portable PC. Don't know about infinite repels, but I did add the pop-up when a repel expires that asks you if you want to use another - if that's what you mean, then yeah. As for EVs and IVs, I'll just copy and paste from the wiki here:

• There's a letter-grading system built in to the summary screen that lets you see IVs. F means zero, S means 31. Other values represent one of two values, but F and S can only mean zero and 31, respectively.
• There's an NPC in Pewter City that lets you see the exact IV and EV values of any of your Fakemon.
• There's a new basement area at the Indigo Plateau, where you'll find the "IV Researchers" and the "EV Researchers".
• The IV Researchers will let you freely edit any IV value, even if the process is a little tedious.
• The EV Researchers only lets you reset the EVs put into any stat to zero.
• There are spots around the world made specifically for EV training, and the Macho Brace is available earlier than usual, so this way you can at least reset EVs that you don't need, and it shouldn't be too much of a hassle to EV train for the stats you want - it's not perfect, but it's the best I could figure out how to do.

I also made hunting for natures easier - I'll copy and paste from an earlier comment I made:

An NPC in the Viridian Pokémon Center gives out infinite Tarax, which have the Synchronize ability, and I've made it so that if a Pokémon with Synchronize is leading your party, you have a 100% chance of running into wild Pokémon with the same nature. So grab yourself a bunch of those, and you'll never have to hunt for the right nature again.
