It's not as bad as I thought. The program is smaller than the installer.
One reason is that this installer includes multiple languages -- European, two Chinese, etc. -- and by opting out of all but English, installed size shrinks.
Actual installed size = ~ 7 MB, and of that, the .chm Help file is almost 2 MB. So, only 5 MB actually needed.
Includes an on-screen keyboard.
The .exe itself went up from 1.5 MB to 3.7 MB. GUI was mostly the same; "enhanced" colors, like I really care about that.
It offers both native install and disk-on-key install, the latter not using the Windows registry. So, as mentioned, you can use it safely as a guest on another host machine. I don't remember if there was a differential choice in v3.15's installer. Maybe you had to choose: D/l the portable, or d/l the native. That would account for larger installer size here.
I suppose I could try a HD install in a different ProgFiles folder, and check size.
I just checked the Registry for the (existing) native install. Only typical user prefs are stored there, like window size/location, and standard stuff like file paths.
The only MRU stored is the filename of the last pw db that was opened, which isn't any secret, and of no use to an attacker who uses the machine after you do. Nothing that in any way would give anyone access to your creds, without the master pw. Decryption is done only on-the-fly in RAM, and *never* stored in the clear on disk, as always.
No major changes to the operation: Here I am, logged in at NS Forum via PWS 3.28 on Flash drive.
The really cool part, as always: I copied my current pw db to the new flash drive folder, and the new install immediately recognized it. Upon launch, it prompted for master p/w -- same pw as the native install -- and Bam! - popped right up.
It would take a while to look into the finely-grained option changes, but it doesn't look like they foobarred anything, and I can live with going from 2 MB to 5 MB. Not exactly bloat. Pdf readers: Foxit v2 @ 4MB, Adobe @ 400 MB -- now, *that's* bloat.
