This is beta version! It has not been tested.

Changes:
o The category filters are now case insensitive.
o Month view didn't show multiple events on the same day correctly. Fixed.
o Weekly recurring events did not take into account the interval when calculating the end date.
o Restoring a backup didn't apply the settings. Fixed.
o Added possibility to create custom categories for skins which support them.
o "Custom category icon path" in advanced options can be used to define a folder for custom icons.
o Added "Open containing folder" for the skin's context menu in the options dialog.
o Added %HF as header format code which will be replaced with the default header text.

May I suggest some idea?

Suggestion:
# "Custom category icon path" add a brower button
# "create custom categories" add a default option, I make some change but don't know how to change back to skin default, and I go to .rainlendar2 folder to delete the categories.ini......
# Does Font color mean color in calendar? But I set the color then the date in calendar disappeared......

1. That's was the plan but then I noticed that the property grid control only supports browsing for files and not folders. I'll have to check if it's possible to create a custom editor for the property.
2. Yes, currently the only way to clear the custom changes is to edit the categories.ini file manually. I was thinking about adding a button to the editor for this but I think the modified categories need to be highlighted also somehow.
3. Does this happen with any color you choose?

Hi!
Do you plan to fix the wrong date problem of Outlook all-day events?

I know what the problem.
It's about localized write in categories.ini so Rainlendar can't distinguish it.
So it works corrcetly only in English version.
This problem also happen in schdule bg setting.

for. e.g.
I set Font_color=green
the ini file show
Font_color=[chinese localized str]
so it can't display.

PS.
Has the restore problem I meet before fixed?

I don't know it's my system problem or Rainlendar's.
Cause the categories function can write in categories.ini sucessfully but I try the restore function it's can't.
Are these 2 function in different method to edit the ini file?
"Write in" and "displace file"?

Ohytos: Are you referring to the issue that if you change your time zone the all day events are moved to incorrect day? I need to make Rainlendar somehow aware of the time zones before the problem can be fixed.

evanade: You are correct. The categories.ini shouldn't contain anything localized but it seems this is not the case. I'll fix that. I'll also take a look at the restore functionality again.
