In no particular order, but the first two I'd love to see sooner rather than later....

1) Remember the number of items to show in a list (and position).
If I select show 100 domains, sites, domains, emails, and so on -- would be nice to remember that when I go back.
Plus, remembering the position. Case in point: changing domain options, I go to page 2 of the domain list and make my changes, go back and now I'm back to page 1 of 10 (rather than page 2 of 50.... for example).

2) Cache/remember the "Apps" list, and just allow updating manually (or, once a week automatically? Don't even need that, honestly)
I have a few clients who host many mini sites under their main account, constantly waiting for the "Apps" screen/list to load every time is annoying; can it be to set to cache/save what was scanned before and if I need to force an update there is a button that can re-scan things? Would save an immense amount of time when going in-and-out of things.

Bonus improvement: alphabetise the list? Please, thank you 🙂

3) DNS changes, a few here...

Can it default to "@" when I don't enter anything into the domain field
Can you auto-append the last "." if I forget - despite the big warning label telling me to add it?
Add more than 1 record at a time, let me add 3-4 records then click save/add.

4) I understand based on how the underlying UI is made so this is unlikely to happen; but it would be good to be able to open a new window for things - if I want to make changes to 2 domains, 3 sites - click and open in new tab for each would be a Godsend.

5) If a site/account has a lot of DBs, I'm sent to the "information_schema" regardless of what database I click through on the phpMyAdmin button; would be good to just have a link to phpMyAdmin from the main Database tab to access all databases for the account (ie; don't need to click through to an individual DB).

Again, none of these are deal breakers - just some nice QoL updates that would stop me cursing so much 🙂
