fix(): multi days conferences are reported only for starting and ending days, not during the whole duration

[davinkevin]

Hello 👋

I think it's a bug because I remember it was different before, but I might be wrong… and if it's the case it's an eventual good improvement to have.

Currently, a conference is reported with two elements in calendar view:

• days are greyed out in the calendar during the conf
• conference is reported in the sub-list when we click on the day

However, for a conference longer than 2 days, there is, imo, an issue:

• only the first and last days are greyed out
• conference is reported in the sublist ONLY for the first and last day

Here, an example for devoxx (be) in October this year:

On first day:

On second day, which is not the last day, list empty where I expect it to have it displayed

As a speaker, this bug prevents to see conflicts properly between conferences.

Thank you for your really good tool, see you all soon 👋
