 ## Getting Started
 
-FreeBSD:
+FreeBSD and Linux:
 
 ```
 % git clone https://gitlab.com/alfix/bsddialog.git
 % cd bsddialog
 % make
 % ./bsddialog --msgbox "Hello World!" 8 20
 ```
 
-Linux:
-
-```
-% git clone https://gitlab.com/alfix/bsddialog.git
-% cd bsddialog
-% make -f GNUMakefile
-% ./bsddialog --msgbox "Hello World!" 8 20
-```
-
 Output:

 ## Utility
 
 **Dialogs:**
 
 --calendar, --checklist, --datebox, --form, --gauge, --infobox, --inputbox,
 --menu, --mixedform, --mixedgauge, --msgbox, --passwordbox, --passwordform,
 --pause, --radiolist, --rangebox, --textbox, --timebox, --treeview, --yesno.
 
 **Manual**
 
  - [bsddialog(1)](https://alfonsosiciliano.gitlab.io/posts/2022-01-26-manual-bsddialog.html)
 
 
 **Examples**:

 ## TODO and Ideas
- 
+
  - menubar feature
  - key callback
  - Right-To-Left text
+ - some terminal does not hide the cursor, move it bottom-right before to getch.
+ - refactor backtitle: multiline, conf.backtitle, WINDOW \*dialog.backtitle.
+ - refactor bottomdesc: WINDOW \*dialog.bottomdesc -> fix expandig screen.
+ - accessibility https://wiki.freebsd.org/Accessibility/Wishlist/Base
+ - add bool conf.menu.depthlines.
+ - implement custom getopt\_long().
+ - refactor/redesign gauge().
+ - improve grey lines expanding terminal (maybe redrawwin() in hide\_dialog()).
+ - more restrictive strtol() and strtoul().
+ - implement global buttons handler.
+ - add/move external tutorial.
+ - implement menutype.min_on.

 .Sh DESCRIPTION
 The
 .Nm bsddialog
-library provides an API to build Text User Interface dialogs and widgets: to
-display messages, to get input and to inform about a computation status.
+library provides an API to build Text User Interface dialogs and widgets.
 .Pp
 .Fn bsddialog_init
 initializes the library, the only functions that can be called before is
 .Fn bsddialog_initconf
 described later.
 After the initialization the input and output should be handled via the library
 API.
-.Fn bsddialog_end
-restores the screen like before
-.Fn bsddialog_init ,
-then it is not possible to use the library functions.
+.Pp
 .Fn bsddialog_init_notheme
 is equivalent to
 .Fn bsddialog_init
 except it does not set the default graphical theme; see
 .Sx Theme
 subsection to set a theme explicitly.
 .Pp
-.Fn bsddialog_error
-returns a string to describe the last error, it should be called after a
-.Dv BSDDIALOG_ERROR
-returned value.
-.Fn bsddialog_clearterminal
-clears the screen.
+.Fn bsddialog_end
+restores the screen like before
+.Fn bsddialog_init .
+After the call is not possible to use the library functions.

+.Dv false
+otherwise.
+.Pp
 .Fn bsddialog_backtitle
 prints
 .Fa backtitle
-on the top of the screen, it is possible to set
+on the top of the screen.
+The function handles
 .Fa conf.ascii_lines
 and
-.Fa conf.no_lines ;
-.Fa conf
-is described later.

+described later.
 .Pp
-Each
-.Fa char*
-argument has to be a well terminated string, it can be a multibyte character
-string depending on current locale, see
-.Xr setlocale 3 .
+.Fn bsddialog_error
+returns a string to describe the last error.
+The function should be called after a
+.Dv BSDDIALOG_ERROR
+returned value.
+.Pp
+.Fn bsddialog_clear
+clears the screen from
+.Fa y .
+.Pp
+.Fn bsddialog_refresh
+useful to refresh the screen after a terminal mode change, see
+.Xr terminfo 5 .
 .Ss Dialogs
 The dialogs have common arguments.
 .Fa text
 is a string printed inside the dialog.
+Each
