smartgit.toolbar.longClickPopupOnly=true

Should I remove the drop-down-click area optionally, so it only can be triggered by long click?

I've implemented that because it offers a quicker way to access certain commands/command variants. Except of OS X (which uses a native toolbar implementation) the dropdown menus are not easily triggerable by accident (small click area), but rather intended to be shown on long click.

(Don't know what you mean with "in the review)

For 17.1 the Changes-view in compact mode will remain read-only. The staging/unstaging requires large changes.

My problem with this keymapping is that you will need to use 2 hands. Using a one-key-combination for the most often used command (go to next change), seems to be better for me - at least for the file compare.

In the Log's Files view please select the toolbar button "View all files of the selected commit.".

For splitting commits there is a different command and the latest build 11129 (Help | Check for Latest Build) implements the split using duplicate commits (according to your suggestion), stopping at the first to discard unwanted parts.

What kind of icon do you suggest?

Sorry, I misunderstood you. The incorrectly named "diverged"-warning will be changed to a "behind checkout target" message.

I've changed the request's title so I better understand what I think is requested.

Do you have an suggestion what the base file changes toolbar button icon should show?
