Knowing that you cannot load it before loading it is quite difficult to guessAlextp wrote:2Hacker
We need to hear Ghisler: can he implement it?
(I don't think he can...)

But :
An intermediate solution could be to have a list of "potential" loadable plugin using the file type filter(1) for the current file.
A popup or a menu can show this list and let the user "try to load" a particular plugin if it fail a popup warn " xxx.wlx not loadable fort this file" and remove it from the list of available plugin for this file. The previously loaded plugin is back !
This solution is doable because we use a list of "potential" plugin that is already exploited by TC. The user chose the plugin to load (try) but do not alter TC forcing a plugin just giving a hint on which one should be loaded next.
(1) The plugin file Filter is the definition done when you add a wlx plugin describing type extension,.... ex: ext=reg|ext=ini|ext=inf
