Latest CLZ news
This is it, the big v11.0 update for your CLZ Movies app. Version 11 is a huge step forward in the customizability of the app. And I am not talking about tweaking the look and feel here, like layout, colors, fonts, etc… No… this time we are giving you the ability to actually customize the database itself, with your own “Custom Fields“!
The Custom Fields feature will let you create your own data fields, to catalog any information for which the app does not have a built-in field. You can create text fields, number fields, date fields, Yes/No toggles, pick list fields and much more.
All fields you create can be edited on a special Custom Fields tab of the Edit Movie screen. The entered data will nicely appear in a special section on the movie details page. And of course, you will be able to use the fields like any built-in fields, that is, sort on them, use pick list, date and toggle fields as folders, search your text fields, etc..
