At the last update (20 August 2018) was turn off calendar view mode: one day agenda (leftmost view button). Instead it now working weekly view. It was the main view mode of the calendar and i suggest to left it. All appointments agenda mode (most right button) is not comfortable cos show appointments before and after this day.

Creating an event or task invariably involves other people and Many other tasks, phone calls, emails, links to websites to be able to complete the task. PI should enable you to do this without leaving the original task on event screen. You should be able to review the 'project ' and update it. How about a Wizard to tailor to meet your needs to refine your project. It would be good to have a link from an email to create the task which initiates the project. This would make PI creative (Brainstorming) and more funtional

I would really like to see the older Day view return. It was far easier for me to see my appointments and to do at a glance without the risk of missing an appointment because I failed to scroll down through the day. You can include the time grid in an extra daily view or have a feature where I can choose the daily view that works best for me.

Sync my PC Outlook (2016) direct to Informant. Or maybe PC to InformantCloud. Existing 3rd party works ok but they are not "Informant" so it feels like I'm getting hit by random costs for different pieces. Just a simple Outlook sync so when I enter an appointment it shows on my calendar, and when I complete a task in informant it shows completed on my Outlook. Single price so I'm not guessing about what to pay or whether it is one-time or annual subscription.

Add a "Navigate Here" item (which would launch Google Maps and navigate there from current location) to the Event menus, both on the calendar view when you long-press to open the little menu with "Edit" "Delete" "Duplicate" etc. also have "Navigate Here", and when you open the event itself, in the Locations drop-down box, have "Navigate Here" in addition to "Show On Map" and "Edit Locations".

The apps mentioned above let you set a flag on an event (and correspondingly mark it as completed), so it will move to the next day if not completed.

New hourly week icon should be adjustable in settings regarding the number of days it applies to from 1 to 7.
You are currently displaying this in a 7-Day format which is not easily readable on a small cell phone.
I believe many people would prefer this view to be adjustable regarding the number of days it displays. I personally would like to see it as a 1-day hourly View to be an alternative to the one-day list View.
This can be done in settings by the user selecting Days 1 through 7.

In IOS I color code my days to know what kind of day it is going to be. For example, am I working or off is a certain color. I was hoping with the new PI5 update I could do this, but it still is not available yet.

Click to open android maps in the address field, like in v.4

Allow users to add the location of event and calculate the distance from their home. Have the distance tracked under the specific tag. This will allow business owners to submit mileage for tax purposes easier. Also have the ability to create a printable report.
