I think the filter of the calendar layout is not 100% correct.

The situation I have is, that my item is more than one month long. (season for hotel pricing) The current filter just displays events which start in the current month. So even a event starting on the last day of the previous month wouldn't be displayed.

Current filter:

{
    "_and": [
        {"start":{"_gte":"###FIRST#

Since we also expose the Skia-bindings for a Canvas-like API I think it might be a good idea to start refactoring the API to utilise more named arguments e.g. ~x=..., ~y=....

What do you others think?

Version: v0.10.0
To reproduce, go to settings and add more than categories at the same time below any category.
When you assign the name for one of the new, the other get the same name.
If you go to the second and try to change the name, the first one gets the second name.
I hope this helps.
Thanks.

A little more explaination (in the form of an xml comment) is needed on format strings like icu_abbrev_wday_month_day_no_year, because they do require to be changed in some languages but translators often break them. We obviously can't expect everyone to understand formatter syntax ;)
