Many shortcuts in SmartGit are window-specific. Look to Edit > Preferences > Keyboard shortcuts, some Commands are prefixed with Window name. The request is to support Ctrl+Shift+C not in the Graph window only, but in the Files window too.

My printscreen is a case where it would be helpful.

But, such a feature should be switchable-off.

Yes, there can be no matching line on the other side, and, vice versa, several matching lines.
If it's possible, highlight them, if any.

In any case (0, 1, >1) this information would help to work with complex code.

Can we highlight the current line on both sides?

When the current line has no differences, such highlighting is simple but not very useful.

Inside changed blocks, highlight line(s) on the other side which contain(s) matching parts with the current.

Moving a Branch to a far Commit can be realized without drag-n-drop, by modifying context menu for Commits:

1. Select Branch "MyBranchName" to move, in Branches window,
2. Right-click on Commit to set Branch to,
3. In context menu, select "Set Branch 'MyBranchName' to this Commit"

One commit is just an example. It could be modified to «N commit(s)».

The topic is about all operations in Smartgit, performed by drag-n-drop in Commits panel, when source & target commits are «far» from each other. So concerned ops are Rebase, Cherry-pick (dragging commits) and Set 'branch_name' to 'commit_id' (dragging branches).

We have a large tree of branches: a master and some supported versions below. I must rebase f.e. 1 commit to the top (master's head). This commit is located f.e. ~10000 lines (commits) under the top. So I drag it and start to scroll Commits panel upwards, holding the mouse button. After several minutes I reach the top and drop it.

If smth unclear I can post video.

Dropping commits onto Branches window is very much required. Currently to rebase to far branch I spend 5 minutes (!) to scroll, keeping mouse button pressed. Then I get conflict, solve it, and scroll 5 min again. Help!!!

Mouse hover over Smartgit icon in task bar: got 2 similar previews.

The `Conflict Solver` window should have its own icon too, f.e. red.
