Which wallet do you like the most? Personally I really like Exodus, the only con is that it's not fully open source, but other than that it's a great wallet!
Are there any wallets which allow you to have multiple addresses?
I have used myetherwallet mew mostly alongwith coinvase but now i have started liking trustwallet because it provides more solutions and options.
Regarding multiple eth wallets you can try Gaurda wallet, they are advanced wallet service with this option.
Yes i am 100% agreed from your suggestion, in fact trust wallet have more suitable options/ solutions than my MEW. BITFI is also fine
