Colocar de alguma forma as os eventos que vão sendo concluídos com algum tipo de marcação diferente, seria ótimo! No mesmo modo que tem das tarefas.

It would be nice to have a memo function to write down tasks by category. Currently, we have to write tasks on a designated date, making it burdensome to write down an unconfirmed schedule.

Repeating tasks, setting a time for a task, and color coding tasks individually like calendar events.

It would be nice to have the update button at the top of the screen next to the add event button for easier access.

Using an Office 365 account and have accepted an Optional invitation, but the event does not show on the calendar. Any way we can allow these if you've accepted the event?

Seria possível criar um widget do calendário para ser exibido na área de trabalho? Faço faculdade e gostaria de poder ver alguns prazos de entregas, eventos e essas coisas de forma mais rápida e prática assim que desbloqueio o computador.

We have the View Option of Week Number. Please add the View Option of Day Number.

allow user to modify color of integrated calendars

Would be nice if the weekly overview would show the place of an appointment

I'd love to send a PDF or Screenshot of my calendar for people to see what slots I have available. I'd love to have the ability to blur my apointments name, and see only the blocks of duration.

Dear Sir/Madam, I am writing to express my appreciation for the quality of your app. Thank you for creating such a useful tool. I have a request. As I come from Ethiopia, I would like to suggest adding the Ethiopian calendar system in addition to the Gregorian calendar system that is currently available on the app. Is it possible for you to consider this request? Thank you for your time and attention. Best regards.

I would underline the option for implement standard-shortcuts like Ctrl+S for Safe ... and so on - of course in windows-inviroments. 

TipTool mit ganzen Terminangaben wäre gut, wenn man auf den Termin zeigt

I would like a feature to mark the tasks as done in the calendar

I would like if possible, for the system ( As an Option as not everyone would like it) for the reminder system in the calendar, to pop up on the desktop or phone not the once and never again, but to be persistent until properly acknowledge not just dismissed. From the the point at which the reminder is set, with a repeat reminder option. ( like a snooze option on an alarm clock.)

I would like to see an option to display the Month View the way Google Calendar does, with All Day items shown in the colored bubbles (like OneCalendar does with everything) and non-all day items shown with a colored dot next to the title.  This makes the Month View much less crowded and easier to read for people with busy schedules.

This applies to all version of OneCalendar

Open two copies of the calendar at once so I can see two months. Many projects, trips go over one month, I would like to be able to see the whole project.  (OneCalendar is 99% perfect already)

Please !! Add this very simple but extremely useful feature. We asked for it 4 years ago also.
