[TYPO3] Typo3 4.2 suggestions

[Darko Jr. Gonzalez]

Heya

I dont know where to post to suggest these two features, which I think 
are kinda important. Among the loads of flexibility and options Typo3 
provides I didnt find these two:

1. Via page properties there are these cache values:
1min, 5min, 15min, 30min, 1h, 4h, 1d, 2d, 7d, 1m
I need 12h, or I found there is clearCacheAtmidnight, but I want to 
optimize it, or put a workaround, so is there a way to set that each day 
at exactly 4pm the page cache is cleared and recached at next visit?

2. I've used abit Joomla, there is a handy section there which allows me 
to disable the website FE for regular preview by a single click. How do 
I achieve that. As far as I know there is no such thing in Typo3, unless 
I do it manually e.g.:
	- hide homepage, but the other pages are accessible directly
	- deactivate the root template. shows template not found for TV, but I 
dont know how to revert back to activated, unless I do undo from the logs.
My suggestion, pretty simple. One click goes under "site maintenance", 
one click goes live back. Eventually that we can set a picture/baner 
while offline/under maintenance - that would be great.


Thanks
