You should read previous suggestions

1) Read previous feedbacks on software informer (idea.informer.com): I found interesting ideas for you, in past months/years.
2) Install the program in another partition, different than C:

The sticky password installer currently installs the program in "c:\program files (x86)\Sticky Password" without giving a choice.
With a junction, I was able to install it in "d:\program files (x86)\Sticky Password".
Give us the liberty to install the program in our preferred location.

3) Better than previous point: make it portable.

4) Possibility to change font/size in the program menus/options: little, medium, big.

5) Allow your users to localize your program.

I'm Italian, I have been using your software for at least six years (maybe more), but it isn't available yet.

6) Change date format: use the month in letters (Jan, Feb, Mar, and so forth)

Different countries use different formats.
Who prefers month-day-year, who prefers day-month-year, who prefers year-month-day, and so forth, will directly know what number is the day and won't be confused by the month number (if it will be written in letters).
In other words, I'd like to see expanded dates.
Examples: "6th December 2018" or "December 6th 2018".
I.e., the month should be written in its entirety.
I can see the license key of your software was valid until 06/12/2018.
Unfortunately, I keep my system in English, but I'm Italian (and I live in Italy).
When I installed the GAOTD version (at the end of 2017?) I was conscious that the premium version was activated until 6 December 2018.
But after some time (a month?) I wasn't able to know when the license expired (6 December or 12 June?), checking the ABOUT window.
Therefore I had to check when I installed it through Control Panel\Programs\Programs and Features or I must have checked when it was available on giveawayoftheday.com.
