The new panel looks nice! If you expect some more input about what is wished for a new panel version, two things come to my mind:
1. A possibility to display anomalies of the galleries/folders configuration. I have around 30 galleries created in X3 and sometimes I lose track of individually configured settings I wanted to try out some time ago. This feature would show me, that I have e. g. 27 galleries designed the same way and 3 galleries differently.
2. A little helper to assist linking to other pages: If not auto-completion, maybe a button that let's us search through the directory and create the correct path. For example, I use this relative-url to link from my blog to the panoramas:
. X3 could assist me here by telling me exactly, how many times I have to write "../"
A browser would - furthermore - help to find the correct path to an image used as a preview thumbnail. As far as I know, I have to put the following code to get the correct picture. Without the numbers (3., 3., 22.) it wouldn't work:
image : 3.events/3.2013/22.london-2013/IMG_9061.jpg
Last thing to mention here is that it would be awesome if X3 would notice whenever I rename a gallery and adjust the links in all pages automatically.
Btw, when can we expect the next update? Maybe already in April?
