Cons
Con No (text) file viewer
Con No explicit bookmark support for directories
It though remembers the visited directories and allows to search in this list in most-recently used order and by name.
Con Mainly for key-board-orientated users
The interface is most naturally navigated by arrows and keystrokes. The target market is software developers.
Con Has no menu bar
Hence it is not well suited for visually orientated users which find or remember commands by using a mouse and a menu. Even the fman's hero Sublime Text uses a menu bar.
Con Requires email address to download
Doesn't say what it will do with this data. It is in contrast to the new laws in Europe where only necessary information is allowed to be collected. A download should not require an email address.
Con Still quite buggy
So, for example, sorting only is remembered if triggered by command and not be clicking the table column header using the mouse.
Con Settings can't be found by the GUI
You need to know which files to edit.
Con Default dark theme
No choice between dull-dark or fresh-light.
Con No portable bundle available
On Windows only a net-installer is available.
Con Folders cannot be sorted by size
Con Cannot access Android device connected by USB
Con Cannot access Android device by FTP
And can never will as this is clarified by developer that this feature will never be added.
Con It doesn't have UNDO function
Very important. When you work with valuable data files, this function can't be ommited.
Con Navigating folders by Ctrl+Tab has considerable delay
Con Browsing Recycle Bin is very slow
Navigating away from Recycle Bin tab and coming back to it reload the Recycle Bin which is very slow as mentioned. Program has an option to open recycle bin in Windows File Explorer, which suggests that developer is aware that opening Recycle Bin is problematic.
Con Confusing
Con Context menu only based on icons
No longer with Onecommander 3.6.43
