Yeah of recent there was a workaround in the bitcoin network that actually has allowed fees to be cheaper for quite a while now and I noticed this when I was constantly getting my transactions confirmed at 1 sat per vbyte in just a couple of minutes. Anyways that being said, Electrum mobile seems kinda behind in a couple of things from fees to bulk broadcast and by bulk broadcast I mean sending to multiple addresses via a single transaction.
You are right, I prefer Electrum on computer.
Let us see how the next update will be, it will be a major update.
Well I know a few wallets that have these features already but I'm an Electrum lover...

so I'm pretty much waiting for when fees are fully flexible on mobile not just that slider.
The fee slider can be flexible in a way that it can give 0.1,....1, 1.1, 1.2, 1.3... sat/vbyte. There are wallets that the fee slider are very flexible. Although, being able to input the fee rate will be very good.
