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: add WINDOW *dialog.backtitle for multiline and fix expanding screen.
• refactor bottomdesc: add WINDOW *dialog.bottomdesc to 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.
• doc: external tutorial, theming guide.
• implement menutype.min_on.
• improve refresh at startup, avoid dialog refresh before drawing text.
• add debug API: bsddialog_debug(y,x,refresh,"fmt",...).
• add mouse support.
• use alarm(2) for bsddialog_pause.
• delete form fieldlen constraint, hide or truncate long field in little screens.
• improve --inputbox autosizing, consider also input length.
• fix --form "" 0 0 0 Label 1 0 Init 1 12 0 0 (with 0 editable field).
• fix --mixedform "" 0 0 0 Label 1 0 Init 1 12 0 0 2 (with 0 editable field).
• add text customization to --hmsg help-message
• check --passwordform fieldlen like --form and --mixedform.
