Relevant to this request, please consider adding an option to edit the gas limit for a transaction. Some dApps fail to provide accurate gas limit suggestions when preforming more sophisticated txs and being able to manually edit the gas limit would be a welcomed addition for your advanced users. Feel free to add a toggle in the settings to activate this feature in order to protect newer users.

This is the 1 missing feature that is stopping me from using Frame as my main wallet. Metamask's new gas UI has an "Advanced" setting that can remember a specific gas value (for both max fee and priority fee). This is very useful in gas was where you need to send the tx as soon as possible, so having the gas price set from before is very useful. It is also important that this "Advanced" setting can be set as default. That way you don't have to click anything else than "sign" to send the tx. Also some presets "Low", "Market", "Aggressive" would be nice to have. Avoid using drop-downs if possible as that takes an extra click which takes precious time.

something like this quick setting

This is important in my opinion as many times when your using DEX changing the gas manually takes up too much time

Let's generalize this and say that to some degree programmable gas would be best. I would imagine different profiles, to say set BASEFEE up or down a couple of percentages, and also priority fee based on the BASEFEE as in BASEFEE*% + K

Preset gas, or a fixed addition on suggested fee will be very useful

It is not a default, it is the "suggested". You can change for it transaction.

However, that being said, it seems that it does not properly update with market conditions because sometimes it should be higher according to some gas estimation websites. Also sometimes the recommended is below 30 gwei and below the current minimum gas price Polygon has set, so it can be frustrating (shouldn't be below that minimum ever).
