There is a new feature of Windows 10 2020 to name the virtual desktops. It may be a helpful in reporting.

I do a lot of work with systems that are Europe based and all of them have weeks start on Monday and end on Sunday (Which I rather like... The weekend, is the weekend, not the week book ends)
Without this capability I'm always fighting the Timesheet and can't use "Previous Week", for example. I always have to use a Custom and set the begin/end dates. I first looked for that feature in Settings -> Display. I don't know if there is a better place.

My workflow is to search for keywords. Sometimes the keywords get tagged with the wrong tag, which I notice when doing a different search. I then need to "delete" tags, and re-tag everything in the search with a different tag. It would be great if instead of "Add tag..." I could "Add and Replace tag..."

When I edit new tag, and key in esc, the edit window is closed and the typed text is gone. In this case please ask to save or forgett the text. Another tip is save text in between with key ctrl-S, not only with OK button.

For the add in call log on Android, it would be nice to be prompted in some way to enter notes about the call which can make it easier to recall events and subjects when tagging later

Conflicts in autotags are taking me forever. There are so many of them. You need a feature that detects them and that has some form of wizard that will scroll through them all and just ask the user to select which is the tag they want most, either on a day basis or by project, or some other way.

It should be possible to specify applications or websites for which no screenshots should be taken.
If you have applications or websites with confident information (such for example password tools or financial tools) it is not desirable that these contents are visible by others in screenshots.

Maybe a Bug or missing Feature.
Using "Tag last untagged time" as described on
https://manictime.uservoice.com/knowledgebase/articles/686274-tag-last-untagged-time

on Windows 10.
The Cursor blinks on the "Tags" input field, but typing do NOT appear there.
Have to click it with the mouse first, then typing works.

Hint: using a shortcut to open the "Tag last untagged time" works better, typing is possible without mouseclick.

Once I finished tracking all periods in a day, I like to select all the rest and assign a generic non-billable task, so I know that the entire day is accounted for. This would make that task much faster.

After working on Task A, you switch to Task B and create the new tags. Then, when you want to switch back to Task A, it would be nice if you could just right click on the previous block of time (or select from the drop down in the corner) to start the timer again for Task A. Instead of having to retype in the popup (just takes more time).

When I export a timesheet to Excel my very next action is to open it in Excel which I suspect is a common next action for many people. Currently it's a manual process; run Excel, locate where I saved the file and open it. If I'm processing many exports this can be a significant percentage of the time spent.
I'm about to write an autohotkey script to automate this for myself however it would be nice if Manictime offered the option to directly open the exported file after saving.

When I ended work at 1.00 AM and turned off computer, and then turned on computer again at 20:00 - Daily Duration chart tells me, that I've worked 20 hours. It should count only time when computer is turned on.

Provide totals at the bottom for Billable and Unbillable time as well as the grand total.

Eliminates some toggling you have to do now to get these numbers.

Expand the Settings -> Tagging configuration to change the way Recent Tags is displayed:

1. Recent Tags (Globally)
2. Recent Tags (Individually)
3. Recent Tags (Filtered for the Application and/or Document being tagged)

3 is huge. If the same Application and/or Document is always tagged the same - why do we still need to sift through the recent tags list each and every time.

Allow any kind of selection on the timeline and provide the ability to scroll through just the images for what is selected optionally removing or re-including the selection covered by the shown image for the final log entry and the end of the process.

I'd like tags to be suggested based on machine learning, so I don't have to come up with rules, I work on many small projects, so creating rules manually is too time-consuming.
I'd like some machine learning to look at past tagging and suggest the correct tag (tags can be those found via the Jira integration, rather than AI making up text)
The machine learning should take into account adjacent tags, and how I've tagged things in the past. there should be a huge wealth of data.
It could also use the screenshots, often a client logo appears on those.
