I compiled XO from source, but Im pretty sure the default version has the same thing.

The tooltip could do with a little shift upwards, above the icons so it doesn't cover them. Even with the mouse over the tooltip the clicks are registered to the correct action so its really just cosmetic.

Whenever a server or pool is needed, so the field doesn't stay empty and requires manual selection.

For example, when creating a new VM, the screen is empty with one line:
Create new VM on: [pull down]

The same goes for some other items but I don't click nearly as much so in particular for creating new VM's it would save some time if a default could be configured.

Thanks!

One pool, one server.

Can I set a default selection for this pool/server when I choose new vm, storage, network?

Thanks :).
