This would be so much easier than adding new tags to distinguish them. I could also make sharing tasks easier -- just share out all tasks in a project to the same set of users. Reporting, likewise, could see some simplification with the addition of project-based organization.

Sometimes when I'm in then middle of a task I get a phone call which I time as well. After this phone call I would like to be able to pick one of the previous tasks and continue that one without having to enter the tag and the comment again.

Create a Firefox browser extension that allows the user to track and edit tasks directly on it. The web sidebar is great but an actual extension would be much better because it could include, among other things, offline tracking and syncing. And a more integrated interface.

I would like to be able to specify an (optional) estimate to a task so that I can compare it with my actual effort. A report should show the difference (actual - estimate) for those tasks that have estimates.

Timer works, but cant add comments.

The total in the timer window counts solely what was enterend in the timer since the timer was last opened. It doesn't consider changes made in "edit entries". Also I´d much rather see the total of the day, rather than "total since last opened"

Provide optional pop-ups, with user-selectable time intervals (e.g. 15 min, 30 min, 1 hours, etc.), that will open a window basically saying "Hey, are you still doing this task?"

I run SlimTimer in a small separate window via the "Bubbles" thing. That window is usually covered by my browser, and I often forget to stop a task when I'm done. I think my suggestion would provide a solution to this problem.

It is often not possible for me to start the Timer "in time". E. g. when my day starts it takes some time until I have the timer open.

In these cases I would like to have the possibility:
1. To start a task in the timer
2. Adjust the start time manually while the task is still active.

A nice addon would be that doing so also adjust the end time of the previous active task in case there is a conflict. This would allow easy adjustment when you have forgotten to start a new task.

This could then be used to start and stop tasks from your iGoogle homepage or just a desktop widget from Google Desktop (you could even put the widget on your own site).

This feature shouldn't be so hard to implement and would definitely get the attention of many people. By just adding the alternative of an internet calendar link (ical), or the option of exporting the outlook entries, people can visualize how they used their time in different platforms such as google calendar, outlook, or the mac calendar. It also brings the alternative of syncing with pocket pc
and other devices instead of having to download a csv.

The current login is done over HTTP which is insecure. An improvement would be to use HTTPS, but my preferred option would be OpenID-enable Slimtimer, so I have one centralised username/password for all websites.

Allow for a task to be paused during periods of no activity. Allow this to be done manually (click a button in sidebar SlimTimer or Bubbles) or detect when a user's computer is idle for X minutes or detect their screensaver.

This will hopefully improve accuracy of time entries by helping to compensate for breaks when a SlimTimer user forgets to stop their timer.

A button to save the options of a personal created report may be useful.

I forgot to Stop my timer at lunch !!
It would be nice I could split one task in two pieces.
(first entry gets a new endtime and the "new" second one started after lunch ;-) )

Being able to manage, edit, delete and merge tags is definitely required. Being able to group or color them would be a nice bonus. Being able to define exclusivity would be a grand bonus (like billed vs non-billable)

The completed task view gets pretty crowded after you've used SlimTimer to track a few projects. Allowing users to archive these tasks in an organized way would help clean things up, leaving the completed view as an area for completed tasks for currently active projects only. This archiving feature could be nicely integrated with the project-based grouping I suggested earlier -- projects that are marked as finished get automatically archived with all their tasks grouped together.

The itunes store has many time tracking apps but the android market has none AFAIK. SlimTimer is one of the best timers I have found and I have looked at many. You could be a serious contender if you were the first on the Android market.

If creating an entry in the afternoon, the start time auto-complete should default to PM rather than AM. Likewise, the end time should be smart enough to know that if I start at 9am and end at '5' I most likely mean 5pm. In other words, assume end time is within 24 hrs of start, and adjust AM/PM accordingly.

This is the only thing preventing me from using slimtimer exactly how I'd want to use it.
