Yahoo mail is not bad at all IMHO.
I don't think that it is coincidence that, whenever someone I know gets their email hacked and used to send SPAM, they are using Yahoo mail.
There was an issue disclosed a few months ago which related to stealing Yahoo credentials -- I suspect there are others. It's either vunlerabilities at Yahoo or there is something about the type of person who uses Yahoo mail.
You tell me you want a house built in two days... Fine... but if you expect there to not be serious problems and unforeseen issues as a result of rushing through the planning phase and then constantly changing the mission premeters throughout development... then you're being unreasonable.
Newsflash
In your scenario, if the contractor signs a contract to build the house in two days, then the contractor is liable if the house is not ready in two days. As the contractor, you should not take on a contractual resposibility that you cannot deliver. That's just as true for building a house as it is for building a large website.
As the contractor, you should have the expertise to decide to refuse the deal if the terms are impossible, or take actions to eliminate the risk.
The first thing I tried to do was to customise the panel. right-button clicking on the panel did nothing. Why? I have later learned that I have to click <alt>-right-button on the panel to have the same effect. But why? How should a user know that s/he needs to also hold down the alt button? What was wrong with a simple right-click, which has been used for decades to bring up a context menu? The right-click has not been re-assigned, it just became non-functional.
The changes make the desktop environment less discoverable and hence less usable. It's this type of change that puts people off.
