Position of Newly Opened Tabs - Chrome Ordering

The default chrome ordering is very well thought of.

Basically, successive links open.

Parent Tab >   (1) 

(2) 

(3)

If you navigate to the child tabs, and then navigate BACK to the parent tab. 

And open some more links, 

Parent Tab >  (1) 

(2)

(3)

(4)

(5)

This is totally expected.

However, if you navigate OUTSIDE of the child tabs listed above, and then navigate BACK to the parent tab, 

and open some more links, we get,

Parent Tab >  (7)

(8)

(1) 

(2)

(3)

(4)

(5)

This is VERY useful IMHO. It allows you to quickly switch to the recent links you opened quickly without traversing all the old child tabs.

Why isn't the ordering simply set to open ALL new links to the right of the parent tab? 

Parent Tab > (5)

(4)

(3)

(2)

(1)

This would greatly simplify the code, wouldn't it?

However, this is not ideal because child tab (5), hasn't finished loading yet. 

So you can't switch to it and start working immediately. 

The current implementation in sidewise implements opening links as the last child of the parent tab. This is great but the default chrome ordering is better. Its rather difficult to get this configuration in firefox too but its possible  when combining multiple extensions.
