adrenochrome's questions

Before, in 12.04&14.04, my download folder was nicely sorted by date : nautilus opened on top of the list with (newer)files first and then folders.

In 16.04 the directories are displayed first which i find annoying :

• order has changed
• i donwload files not directories, directories are the result of archives extractions and are not relevant for accessing to new downloads.
• i'm obliged to manually scroll or press end key to access the last downloaded file

There is an option in nautilus called "sort-directories-first", but when disabled it result in file&directories mixed together instead of files first.

What are the ways, if exists, to revert to the traditional sorting method "file first" ?

When i want to run the calculator, i click on unity first icon (dashboard?), and then i start to type :

ca : is showing the calculator as first result (probably because zeitgeist recorded that its the app i use the most)
cal : is still showing the calculator as first result
calc : is showing libreoffice calc as first result

It's annoying because if i hit "enter" libreoffice calc is launched :(

I tried to blacklist libreoffice calc in "activity log manager" but the behavior didn't change.
So the main question is :
How to prevent libreoffice calc to show up as first result without removing it completely from unity ?
And to go further :
Why is it showing up as first result on search with "calc" and not with "cal" or "ca" ?

I just discovered that zenity support html tags.

zenity --error --text "hello <b>world</b>"

but how to make it work with entry type ?

zenity --entry --text "hello <b>world</b>"

It's printing tags instead of interpreting them.
