Yes... this is exactly the problem... hundred people, hundred opinions
Without suggesting I prefer one or the other let me just mention a few points, which some of you might not realize:
1. some people have lot of blocks, having a description of everything will make each block much larger in terms of space
2. one thing many of you probably dont realize is that in a sense you are very lucky - lucky because I have decided to use your native language as the template default - in other words, the strings appear ok for you without having to wait for translation to be available, installing it etc. But remember you are a minority, over 50% of users use the template in a different language. Now let's just assume that I decided to have English as just an additional language, and default Czech. This would happen then - you would install this block and at the top you would see "klikněte na pohyblivý posuvník pro posun předpovědi" - great isnt it
And you would have to wait before someone provides translation (or provide it yourself), then wait before I add it to the translation database and then update your language files. And this would happen with every single string. This is a major issue. I try to use icons wherever possible, try to avoid as much as possible long strings, and try to use the already available ones. This is also because the more language strings there are, the more people are discouraged from even translating something - they see a very long list and just say - "oh, Im not doing that". From my perspective this is not a problem, but...
3. on the other hand I understand that in some cases some people find it not so intuitive
4. I can add customizations to the template, but only to a certain extent. I simply cannot let you set every single font color, every section of the block, this would create infinitely long settings pages, hours of work for me and I think that unless you write all the code yourself, you will simply never have 100% what you like - and this is by no means just a problem of Meteotemplate
5. to make things worse, as you can see, even if I think I found a solution (tooltip), someone points out a scenario, where this will not work (touchscreen displays)
This was not to say I prefer one or the other soluton, just summarizing the situation, if anyone has any ideas, Im happy to hear them, but when I look at it, I personally think the only solution is some sort of a compromise, which will never 100% suit everyone
