Redmine

Ah, good point. But isn't the common denominator that the ticket gets assigned to you?

I think the main problem is that right now, if you want to claim a ticket (an extremely common task in issue management), you have to go through a 4-click process after the point of viewing an open issue:

1. Click Update
2. Click the "Assigned to" Select List
3. Click your own name in the "Assigned to" select list (after finding it, which can be a pain on large projects)
4. Click Save

when other apps, including Unfuddle, make this common task as simple as possible.

Just a thought:

In the global settings, under the repositories tab, Redmine currently has the ability to set some basic rules for "Referencing and fixing issues in commit messages".

Could we create a basic rules section for "Accepting" a ticket that operated similarly, except put it within each project's Settings?

This gives you the ability to create project-specific rules for what happens when you accept a ticket.

We were facing pretty much the same problem (migrating from TRAC and missing the accept button), so we created a plugin that does the accepting in one click (change status, change user, submit changes). It is neither much code nor very fancy, but perhaps you find it useful: https://www.redmine.org/plugins/accept
