The used GUI library (SWT) and hence SmartGit only supports one scaling for all monitors. SmartGit only supports images at 100% and 200% scaling.

It is there - see the Hamburger menu. You need to unselect the Compact mode.

Do you change all 35k files in the commit or do you have enabled to show even the unchanged ones?

By default, for a file log, the file is preselected in the Files view. Why hide all the other files?

If it is about commits, just select the two commits to compare.

Disabling is not possible (and probably won't), but maybe the preferences option "Preselect 'Staged' if files are staged, even if a file without staged changes is selected" helps you. I also recommend you to select View | Separate Working Tree and Index.

> In all three cases the search will be performed within the files remained on previous step (as now it is shown in Files-panel).
In some cases, e.g. 2 selected commits in the Graph, one entry in the Files table could mean multiple files (file states). In which one to search?

Could you also please describe your usecase - why you need this feature?
