Pane/Variable Pane you are right, normally I use multiple panes in a variable pane and that was the reason it worked for me.
Translation, the example of translation I used in the "timeline" is very nice for small application, however I placed all translations from all application in one mySQL table, which is still growing (at this moment about 1500 items per language) and I have some performance problems. So I'm thinking about other solutions of getting the translating:
Navigation, the idea of a vertical tabbed pane I would like it, but the only difference with the horizontal tabbed pane is the direction, so maybe a property/variable (horizontal/vertical) is more useful.
