### Describe the improvement

Hello,

I am working in a area that don't have proper internet connection. most of the time I download with mobile Internet which is limited.

When i download offline installer it saves the file by Different names.

The Problems i have

1. Sorting by name (Example "setup-lightshot-5.5.0.7", the word setup attached at front causing sort by name to fail. it takes time to find package, when there are lots of package in the folder.)

2. Not able to identify by version Like some installers don't have version attached to the file name if some newer version is available on uniget it gets difficult to verify the offline installer version as the file name does not have the version Like "SpotifyFullSetupX64", "BraveBrowserStandaloneSilentSetup", "googlechromestandaloneenterprise64" etc.

3. Older version gets overwritten (related to point 2. when the file name does not have version it gets overwrite by newer installer.)

If possible, make this simple change so that every version gets proper name and newer installer does not overwrites older version.

Thanks for doing good work. Hope to implement this simple and good feature for Download Installer function.

### Describe how this improvement could help users

It will help user to identify the download installer versions. and it keeps version distinct and don't overwrite previous version those who download offline installers .it will be great help.
