Congrats on the easy feeding!
Honestly, I'd recommend leaving her in her normal enclosure when you feed her. It's less stressful overall and you don't have to worry about moving her right after she's eaten. Cage aggression when feeding is over-rated. My girls all know that unless there's a rat on the end of a pair of tongs, there's nothing to strike at when my hand goes in. For now, I'd give her at least 30 minutes before you put her back.
The general rule of thumb on when you can handle them after feeding is 48 hours. If it was a large meal though and you can still see a lump, it would be beneficial to wait longer to handle. Handling too soon can cause regurgitation, which can damage your little one's throat and is extremely stressful.
The best thing that you can do for your new little one is to leave her be and avoid handling her for the next couple of weeks (outside of what is needed for maintenance - cleaning poop, urine, changing water, etc). My rule with new arrivals is hands-off until three consecutive meals - if there is a meal refusal, then the count starts over. Being in a new environment is stressful enough without a monster yanking them out from their nice, comfortable hide.
