Vape is already very optimized, believe it or not. The very nature of Vape (being an injectable client) makes it very hard to optimize, but in almost every update we've pushed, there are code optimizations and other "behind the scenes" stuff that aims to make the client run faster.
We are open to adding more features to Vape V3, but at this point we've pretty much exhausted the list of potential features to add. Nearly everything that could be even considered slightly useful to any of our customers is already in Vape V3, and anything that we haven't added yet is almost certainly not in the client because it'd just clutter up the client and no one would use it. If you have any suggestions for features you'd like to see in the client you can post them over at our
suggestions subforum.
TL;DR: We are still actively working on and updating all of our products. We have slowed down considerably as of late because (at least in our opinion) there isn't much left to add to our products. If you have any ideas on what we should add next we'd love to hear your suggestions.
