-Could double-clicking on the unit/building/what-have-you listed in the column on the left bring up the Pedia page that now needs to be accessed through the Tools menu? That would be very convenient.
You can keep the pedia windows opened. So you can just click on the list, and the pedia windows will update immediately. You can also just select something in the list, and then use the arrow key to quickly go through the list, and see the pedia windows.
Hmm... On a side note, my screen is 1900x1600, so I can easily have both windows on the screen at the same time.
-It is handy to have that Pedia page report what is included in the .txts and .inis, but do you plan to incorporate editor functions? Particularly for the PediaIcons and Civilopedia .txts? (e.g. the ability to 'Browse...' and select the large and small icons, the unit's .ini etc, and also to directly edit the descriptions for the unit in the Civilopedia)
Not planned. But if you edit the pediaicon.text, save, and then reselect the item in the editor, the pedia window will be updated immediately.
Usually when modding, I have my editor and the pediaicon opened at the same time, as well as the explorer.
If I see an error (red line in the pedia window), I look in this windows to see the error. Then I go to the pediaicon.txt, if necessary I locate the line (select the Pedia entry in my editor, copy and paste in the find of notepad), correct the error, and then just select again the item in my editor, and check in the pedia window that the text has been corrected.
-I know it's been said, but: it would be useful for the windows to be resizable with scroll bars. As is, it completely fills my 1024x768 screen, covering the task bar.
Buy a bigger screen
-An 'Export' or 'Save As...' button within the Export window would be intuitive, I think (unless I missed it?)
There is an Export window??
